(l64a): Add example.
* posix/unistd.h: Correct value for _POSIX_VERSION.
* sunrpc/Makefile (defines): Remove definition.
* sysdeps/ieee754/nan.h: Correct typo.
1997-06-04 10:50 Fila Kolodny <fila@ibi.com>
* posix/unistd.h: Add definition of __fchdir corresponding to fchdir.
* login/utmp_daemon.c: Correct location of utmpd.h.

* Makerules: Rename $(common-objpfx)distinfo-$(subdir) to
$(objpfx)distinfo.
* rpm/Makefile (distinfo): Adapted.
1997-06-03 18:32 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* rpm/Makefile (install-slib): Collect shared libraries here
instead of in install-lib, including libc.
(instvars): Add slib.
1997-06-03 18:23 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>

* math/libm-test.c (cpow_test): Add epsilon for long double in
test for 2^10.
(identities): Add epsilon for float in second identity test.
* sysdeps/m68k/huge_val.h: Change GCC's HUGE_VAL{,F,L} to use
DI and SI mode integers instead of bytes. Fix value of HUGE_VALL.
* sysdeps/m68k/nan.h: New file.
* sysdeps/m68k/fpu/__math.h (isgreater, isgreaterequal, isless,
islessequal, islessgreater, isunordered): Fix assembler syntax.
* sysdeps/m68k/fpu/fraiseexcpt.c: Do it right so that gcc doesn't
optimize out the operations.
