Update.
1998-07-29 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* manual/pattern.texi (More Flags for Globbing): Fix typo.
* manual/math.texi (Special Functions): Fix typo.
* sysdeps/unix/sysv/linux/bits/in.h (IPV6_ROUTER_ALERT): New
constant from Linux 2.1.112.
* posix/Makefile (install-lib): Compile libposix.a only if
build-static == yes.
1998-07-28 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/generic/glob.c: Maintain const correctness. Move extern
declarations to file level. Cope with unsupported
_SC_GETPW_R_SIZE_MAX.
1998-07-29 Ulrich Drepper <drepper@cygnus.com>
* stdio-common/tst-printf.c: %z is now recognized by printf.

errors.
* sysdeps/libm-ieee754/c_csqrtf.c: Likewise.
* sysdeps/libm-ieee754/c_csqrtlc: Likewise.
Patch by Stephen L Moshier <moshier@mediaone.net>.
* math/libm-test.c (csqrt_test): Correct typo in one test, add
another one.
* sysdeps/unix/sysv/linux/bits/siginfo.h: Adjust siginfo_t after
latest kernel change.
