1997-06-21 02:48 Ulrich Drepper <drepper@cygnus.com> * config.h.in: Add DO_STATIC_NSS. * config.make.in: Add build-static-nss. * elf/eval.c: Use __getdelim instead of __getline. * locale/programs/locale.c: Correct comment. * manual/libc.texinfo: Update copyright and date. Remove A4 option. * sysdeps/libm-ieee754/k_standard.c: Always return HUGE_VAL for gamma overflow. * sysdeps/libm-ieee754/w_gamma.c: Handle SVID and ISO C behaviour. * sysdeps/libm-ieee754/w_gammaf.c: Likewise. * sysdeps/libm-ieee754/w_gammalp.c: Likewise. * po/ko.po: Update. 1997-06-13 10:06 Richard Henderson <rth@tamu.edu> The Great Bit File Move: * configure.in (AC_INIT): Look in include/ for features.h. (sysnames): Add include as the final search directory. (AC_OUTPUT): Create a bits directory in the build directory. * Makeconfig (CPPFLAGS): Look in include/ for libc-symbols.h. * Makefile: Make sure the target directory exists when installing <gnu/stubs.h> and <gnu/lib-names.h>. * csu/Makefile: Use $(compile.S) and $(compile.c) instead of invoking $(CC) directly, as the former have the full include path. * ansidecl.h: Removed. * aliases.h:
