Update.cvs/libc-ud-971112
1997-11-13 01:07 Ulrich Drepper <drepper@cygnus.com>
* manual/arith.texi: Update documentation according to most recent
ISO C 9X draft.
Document fma, fdim, fmin, and fmax.
* manual/math.texi: Allow multiple defitino of mul etc.
* math/complex.h (I): Define using _Complex_U not _Imaginary_I.
* math/libm-test.c: Add tests for fma.
* math/math.h: Describe DECIMAL_DIG macro. Pretty print.
* sysdeps/alpha/fpu/bits/mathdef.h: Define INFINITY as of type float.
Define DECIMAL_DIG.
* sysdeps/generic/bits/mathdef.h: Likewise.
* sysdeps/i386/bits/mathdef.h: Likewise.
* sysdeps/m68k/fpu/bits/mathdef.h: Likewise.
* sysdeps/powerpc/bits/mathdef.h: Likewise.
* sysdeps/sparc/fpu/bits/mathdef.h: Likewise.
* sysdeps/ieee754/bits/nan.h: Define NAN as of type float.

1997-11-12 17:50 Ulrich Drepper <drepper@cygnus.com>
* sunrpc/xcrypt.c: Don't process #ident preprocessor instruction.
Reported by Philip Blundell <pb@nexus.co.uk>.
* string/strndup.c: Use K&R like definition.
* sysdeps/unix/sysv/linux/getcwd.c: New file. Use kernel information
instead of longish search for the name.
* sysdeps/posix/getcwd.c: Add support for use of the code as a
backup solution.
1997-11-12 15:31 Philip Blundell <pb@nexus.co.uk>
* sysdeps/unix/sysv/linux/arm/sysdep.h (SYS_ify): Don't add
SWI_BASE in twice.

1997-11-12 16:08 Ulrich Drepper <drepper@cygnus.com>
* intl/loadmsgcat.c [_LIBC] (fstat): Don't define as __fstat since
now we have a definition as _fxstat.
* libio/fileops.c: Likewise.
* libio/oldfileops.c: Likewise.
Reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>.

1997-11-11 Paul Eggert <eggert@twinsun.com>
Add overflow checking for 64-bit time_t and 32-bit int.
* time/time.h (__offtime): Now returns int.
* time/offtime.c (__offtime): Return nonzero if successful;
check for tm_year overflow.
(DIV): New macro.
(LEAPS_THRU_END_OF): Handle negative years correctly.
* time/tzset.c (__tz_convert): Return NULL if offtime cannot convert.
* time/mktime.c (ranged_convert): New function.
(ydhms_tm_diff): Return nonzero if TP is null.
(__mktime_internal): Handle cases correctly even if they are near or
past the limits of time_t values that can be broken down to struct tm.
(print_tm, check_result, main): Diagnose localtime failures.
* manual/time.texi: Document the fact that localtime returns 0
if the time can't be represented.
1997-11-12 06:03 Ulrich Drepper <drepper@cygnus.com>
* time/strftime.c (memset_space, memset_zero): Use MEMPCPY, not
mempcpy. Patch by Ken'ichi Handa <handa@etl.go.jp>.

* manual/arith.texi: Document copysign, nextafter and nan.
1997-11-06 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* test-installation.pl: New file. Tests for some installation
problems.
