libstdc++: Make _GLIBCXX_HOSTED respect -ffreestanding [PR103626]
This allows the library to switch to freestanding mode when compiling
with the -ffreestanding flag. This means you don't need a separate
libstdc++ build configured with --disable-hosted-libstdcxx in order to
compile for a freestanding environment.
The testsuite support files cannot be compiled for freestanding, so add
-fno-freestanding to override any -ffreestanding in the test flags.
libstdc++-v3/ChangeLog:
PR libstdc++/103626
* acinclude.m4 (GLIBCXX_ENABLE_HOSTED): Define _GLIBCXX_HOSTED
to __STDC_HOSTED__ for non-freestanding installations.
* configure: Regenerate.
* include/Makefile.am (${host_builddir}/c++config.h): Adjust
grep pattern.
* include/Makefile.in: Regenerate.
* testsuite/lib/libstdc++.exp (v3-build_support): Use
-fno-freestanding.
* testsuite/libstdc++-abi/abi.exp: Likewise.
