1997-06-04 20:57 Ulrich Drepper <drepper@cygnus.com> * manual/string.texi: Add comments to discourage use of index and rindex. (strtok, strsep): Apply function on copy of the strings in example. (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. 1997-06-03 19:16 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * 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> * login/Makefile (libutil-routines): Add updwtmp. 1997-06-03 16:16 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * monetary.h: New file, needed for localedata/tst-fmon.c. 1997-06-02 20:31 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. * sysdeps/libm-ieee754/s_nan.c: Use NaN macro instead of static constant. * sysdeps/libm-ieee754/s_nanf.c: Likewise. * sysdeps/libm-ieee754/s_nanl.c: Likewise. * math/carg.c [NO_LONG_DOUBLE]: Add alias for long double function. * sysdeps/libm-ieee754/s_erf.c: Likewise. * sysdeps/libm-ieee754/s_fdim.c: Likewise. * sysdeps/libm-ieee754/s_fmax.c: Likewise. * sysdeps/libm-ieee754/s_fmin.c: Likewise. * sysdeps/libm-ieee754/s_log2.c: Likewise. * sysdeps/libm-ieee754/s_nan.c: Likewise. * sysdeps/libm-ieee754/s_remquo.c: Likewise.
