Update.
1998-04-07 17:50 Zack Weinberg <zack@rabi.phys.columbia.edu> * glibcbug.in: Report version of gcc in use. Remove unused variable ENVIRONMENT. 1998-04-07 Gordon Matzigkeit <gord@profitpress.com> * aclocal.m4 (LIBC_PROG_BINUTILS): Use `-print-prog-name', not `-print-file-name' to find as and ld. 1998-04-07 Ulrich Drepper <drepper@cygnus.com> * sysdeps/posix/mkstemp.c (mkstemp): Correct return value in case template is wrong. Remove unused varaible `ignored'. 1998-04-07 Andreas Jaeger <aj@arthur.rhein-neckar.de> * libc.map: Export __libc_sa_len. * iconv/gconv_conf.c (MAXPATHLEN): Define correctly.
