Update.
1998-03-27 22:46 Ulrich Drepper <drepper@cygnus.com> * Rules: Allow Makefiles to specify test-static for tests which cannot be linked dynamically. * math/Makefile: Move atest-exp, atest-sincos, atest-exp2 to tests-static. * libc.map: Add __nss_passwd_lookup, __nss_group_lookup, __nss_next. * misc/error.c: Pretty print. 1998-03-27 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makerules (libc_nonshared-name): Remove variable. (installed-libcs): Use libc-name instead. ($(inst_libdir)/libc.so): Likewise. Remove explicit reference to dynamic linker. * Makeconfig (link-libc): Link against libc_nonshared.a instead of libc.a. Remove explicit reference to dynamic linker. 1998-03-27 Ulrich Drepper <drepper@cygnus.com> * iconvdata/iso8859-1.c (gconv): Add cast to assignment from char to wchar_t. * iconv/iconv_prog.c: Correctly test for write failure. * iconvdata/Makefile: Add rules for EUC-KR, UHC, and JOHAB conversions. * iconvdata/gconv-modules: Likewise. * iconvdata/euckr.c: New file. * iconvdata/johab.c: New file. * iconvdata/ksc5601.c: New file. * iconvdata/ksc5601.h: New file. * iconvdata/uhc.c: New file. Contributed by Jungshik Shin <jshin@pantheon.yale.edu>. * libio/fileops.c (_IO_file_fopen): Interpret x flag to fopen. * stdio/fopen.c: Correct handling of 'x' flag. Reported by Jason M. Petry <jason@ps.ohio-state.edu>. 1998-03-27 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sunrpc/rpc/key_prot.h: Prevent warning by unknown pragma ident. * sunrpc/rpcsvc/key_prot.x: Likewise. * sunrpc/key_prot.c: Likewise. 1998-03-27 13:49 Ulrich Drepper <drepper@cygnus.com> * sysdeps/i386/bits/string.h: Correct things which never worked. * sysdeps/i386/i486/bits/string.h: Add clobber marks. Patches by Bernd Schmidt <crux@Pool.Informatik.RWTH-Aachen.DE>. 1998-03-27 Ulrich Drepper <drepper@cygnus.com> * intl/textdomain.c [_LIBC]: Define strdup only if not yet defined.
