doesn't use __*ieee128 APIs
I've just tried to build libgfortran on an old glibc system
(gcc112.fsffrance.org) and unfortunately we still have work to do:
[jakub@gcc2-power8 obj38]$ LD_PRELOAD=/home/jakub/gcc/obj38/powerpc64le-unknown-linux-gnu/libgfortran/.libs/libgfortran.so.5.0.0 /bin/true

/bin/true: symbol lookup error: /home/jakub/gcc/obj38/powerpc64le-unknown-linux-gnu/libgfortran/.libs/libgfortran.so.5.0.0: undefined symbol: __atan2ieee128
While we do use some libquadmath APIs:

All these should for POWER_IEEE128 use atan2q@QUADMATH_1.0 etc.
It seems all these come from f951 compiled sources.
For user code, I think the agreement was if you want to use successfully
-mabi=ieeelongdouble, you need glibc 2.32 or later, which is why the Fortran
FE doesn't conditionalize on whether glibc 2.32 is available or not and just
emits __WHATEVERieee128 entrypoints.
But for Fortran compiled sources in libgfortran, we need to use
__WHATEVERieee128 only if glibc 2.32 or later and WHATEVERq (from
libquadmath) otherwise.
The following patch implements that, adds -fbuilding-libgfortran option
similar to e.g. -fbuilding-libgcc used when building libgcc and if
that option is set and the TARGET_GLIBC_{MAJOR,MINOR} macros indicate
no glibc or glibc older than 2.32, it will use the libquadmath APIs
rather than glibc 2.32 APIs.

* trans-types.c (gfc_init_kinds): When setting abi_kind to 17, if not
targetting glibc 2.32 or later and -fbuilding-libgfortran, set
gfc_real16_is_float128 and c_float128 in gfc_real_kinds.

already set.

On a glibc 2.32+ build, we still use some libquadmath APIs
when we shouldn't:

this is not set for Fortran.

Although we build the library with GCC which is known to support
_Static_assert this might be done on a system without the macro
mapping static_assert to the compiler keyword.
The use of static_assert introduced with r12-6126-g3430132f3e82
causes bootstrap to fail on such targets, fixed by using the keyword
directly.

instead of via the static_assert macro.

Fortran 2018 added some synonyms to the existing values, namely
IEEE_NEGATIVE_SUBNORMAL (which is the same as IEEE_NEGATIVE_DENORMAL)
and IEEE_POSITIVE_SUBNORMAL (same as IEEE_POSITIVE_DENORMAL). When they
were added to the C side, they were not kept in sync with the Fortran
part of the library. Thew new values are not used (yet), so it is
currently harmless, but better fix it.

The logic for detection of REAL(KIND=16) in kinds-override.h made
assumptions:
-- if real(kind=10) exists, i.e. if HAVE_GFC_REAL_10 is defined,
then it is necessarily the "long double" type
-- if real(kind=16) exists, then:
* if HAVE_GFC_REAL_10, real(kind=16) is "__float128"
* otherwise, real(kind=16) is "long double"
This may not always be true. Take the aarch64-apple-darwin port,
it has double == long double == binary64, and __float128 == binary128.
We already have more fine-grained logic in the mk-kinds-h.sh script,
where we actually check the Fortran kind corresponding to C’s long
double. So let's use it, and emit the GFC_REAL_16_IS_FLOAT128 /
GFC_REAL_16_IS_LONG_DOUBLE macros there.
libgfortran/ChangeLog:
* kinds-override.h: Move GFC_REAL_16_IS_* macros...

Functions from <ctype.h> should only be called on values that can be
represented by unsigned char. On targets where char is a signed type,
some of libgfortran calls have undefined behaviour.
The solution is to cast the argument to unsigned char type. I’ve defined
macros in libgfortran.h to do so, to retain legibility of the library
code.

gfortran uses internally a different array descriptor ("gfc") as
Fortran 2018 alias TS291113 defines for C interoperability via
ISO_Fortran_binding.h ("CFI"). Hence, when calling a C function
from Fortran, it has to be converted in the callee - and if a
BIND(C) procedure is written in Fortran, the CFI argument has
to be converted to gfc in order work with the rest of the FE
code and the library calls.
Before this patch, part was handled in the FE generated code and
other parts in libgfortran. With this patch, all code is generated
and CFI is defined as proper type - visible in the debugger and to
the middle end - avoiding both alias issues and missed optimization
issues.
This patch also fixes issues like: intent(out) deallocation in
the bind(C) callee, using the CFI descriptor also for allocatable
and pointer scalars and for len=* character strings.
For 'select rank', it also optimizes the code + avoid accessing
uninitialized memory if the dummy argument is allocatable/a pointer.
It additionally rejects passing a descriptorless type(*) to an
assumed-rank dummy argument. [F2018:C711]

This code inlines the size0 and size1 libgfortran calls, the former is still
used by libgfortan itself (and by old code). Besides permitting more
optimizations, it also permits to handle assumed-rank dummies better: If the
dummy argument is a nonpointer/nonallocatable, an assumed-size actual arg is
repesented by having ubound == -1 for the last dimension. However, for
allocatable/pointers, this value can also exist. Hence, the dummy arg attr
has to be honored.
For that reason, when calling an assumed-rank procedure with nonpointer,
nonallocatable dummy arguments, the bounds have to be updated to avoid
the case ubound == -1 for the last dimension.

It turned out that enabling the -Wmissing-include-dirs for libcpp did output
too many warnings – at least as run with -B and similar options during the
GCC build and warning for internal include dirs like finclude, unlikely of
relevance to for a real-world user.
This patch now only warns for -I and -J by default but permits to get the
full warnings including libcpp ones with -Wmissing-include-dirs. It
additionally documents this in the manual.
With that change, the -Wno-missing-include-dirs could be removed
from libgfortran's configure and libgomp's testsuite always cflags.
This reverts those bits of the previous
commit r12-3722-g417ea5c02cef7f000e66d1af22b066c2c1cda047
Additionally, it turned out that all call to load_file called exit
explicitly - except for the main file via gfc_init -> gfc_new_file. The
latter also output a file not existing fatal error, such that two errors
where printed. Now exit is called in line with the other users of
load_file.
Finally, when compileing with "nonexisting/file.f90", first a warning that
"nonexisting" does not exist as include path was printed before the file
not found error was printed. Now the directory in which the physical file
is located is added silently, relying on the file-not-found diagnostic for
those.

The GNU Fortran manual documents that the c_float128 kind corresponds
to __float128, but in fact the implementation uses float128_type_node,
which is _Float128. Both refer to the 128-bit IEEE/ISO encoding, but
some targets including aarch64 only define _Float128 and not __float128,
and do not provide quadmath.h. This caused errors in some test cases
referring to __float128.
This patch changes the documentation (including code comments) and
test cases to use _Float128 to match the implementation.
