Update.
1997-06-26 02:06 Ulrich Drepper <drepper@cygnus.com> * Makerules ($(common-objpfx)libc.so): Use $(load-map-file) in dependency, not $(libc-map). * sysdeps/posix/mk-stdiolim.c: Pretty print. 1997-06-25 15:54 Fila Kolodny <fila@ibi.com> * sysdeps/posix/Makefile ($(common-objpfx)bits/stdio_lim.h): Don't conditionalize this on whether we are cross-compiling. 1997-06-21 15:47 H.J. Lu <hjl@gnu.ai.mit.edu> * elf/dl-lookup.c (do_lookup): Use default definition for a default versioned symbol. * elf/dl-version.c (_dl_check_map_versions): Set the hidden field. * elf/dlvsym.c (__dlvsym): Set the hidden field to 1. * elf/link.h (r_found_version): Add the hidden field. * math/test-matherr.c: New file. * math/Makefile (tests): Add test-matherr. (libm-support): Put back s_matherr. (static-only-routines, aux): Remove s_matherr.
