Optimize termination of floating-point scanning. * stdio-common/tstscanf.c (main): Add new test to scanf to test scanning float values with given width. * stdlib/strtod.c: Add handling of floating-point numbers in hexadecimal notation. * stdlib/stdlib.h: Use __USE_ISOC9X feature macro for new long long functions. Pretty print #if directives. * string/string.h: Pretty print #if directives. * sysdeps/ieee754/dbl2mpn.c: Update copyright. * sysdeps/ieee754/ldbl2mpn.c: Likewise. * sysdeps/ieee754/mpn2dbl.c: Likewise. * sysdeps/ieee754/mpn2flt.c: Likewise. * sysdeps/ieee754/mpn2ldbl.c: Likewise. * sysdeps/unix/sysv/linux/poll.c: Implement poll function by falling back to select-based implementation if syscall isn't available. * sysdeps/unix/sysv/linux/syscalls.list: Add s_poll. * time/leapseconds: Update from tzdata1997b. * time/zic.c: Update from tzcode1997b. 1997-03-01 15:08 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * time/Makefile $(tzfiles:%=$(objpfx)z.%): Remove unneeded depedencies between installed $(tzlinks) and $(tzbases) files. 1997-03-01 14:27 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * math/math.h: Make compatible with traditional preprocessor; requires carefull placement of whitespace in macro arguments. Use __CONCAT instead of ##. Declare long double functions only if __STDC__ or __GNUC__. * math/mathcall.h: Avoid whitespace before argument of macro call that is used as function name. * sysdeps/m68k/fpu/__math.h: Use __CONCAT instead of ##. (__m81_u, __m81_inline): Depend on __LIBC_M81_MATH_INLINES instead of __NO_M81_MATH_INLINES. [!__LIBC_M81_MATH_INLINES]: Don't define internal functions starting with __ieee754.

(make_siglist-CFLAGS): New variable. * Makerules (ALL_BUILD_CFLAGS): Renamed from BUILD_CFLAGS, leaving the old name for the user to pass additional flags to the host compiler. Fix reference to config header. (native-compile, common-objdir-compile): Rewritten to make more generally usable. * sysdeps/unix/sysv/sysv4/solaris2/Makefile: Set ALL_BUILD_CFLAGS instead of BUILD_CFLAGS. * sysvips/sys/ipc.h: Warn if needed feature select macro are not defined. 1997-02-27 17:11 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sunrpc/Makefile ($(objpfx)rpc-proto.d, $(objpfx)rpc-proto.c): New rules to generate dependencies for the RPC service objects. 1997-02-27 16:26 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * argp/argp-parse.c (parser_finalize): Always set *END_INDEX if supplied. 1997-02-28 03:27 Ulrich Drepper <drepper@cygnus.com> * stdlib/strtod.c (STRTOF): Make sure return value is large enough so that clearing second word is necessary. * sysdeps/unix/sysv/linux/netinet/in_systm.h: Don't use kernel header since it is wrong for 64 bit systems.
