2001-08-29 Ulrich Drepper <drepper@redhat.com> * nis/nis_findserv.c (__nis_findfastest): Don't fail if reply received first is from a previous call. Patch by Alexander Belopolsky <alexb@rentec.com> for [PR libc/3670]. 2001-08-29 Andreas Schwab <schwab@suse.de> * sysdeps/ia64/fpu/libm-test-ulps: Updated. 2001-08-25 Maciej W. Rozycki <macro@ds2.pg.gda.pl> * config.make.in (INSTALL_SCRIPT): Define. * Makeconfig (INSTALL_SCRIPT): Define. * Makerules (do-install-script): New macro to install scripts using INSTALL_SCRIPT. (install-bin-script): New rule to install scripts with do-install-script. (install-bin-script-nosubdir): New rule. (install-no-libc.a-nosubdir): Add install-bin-script-nosubdir. (distinfo-vars): Add $(install-bin-script). * Rules (others): Likewise. * Makefile (glibcbug): Install with install-bin-script. * debug/Makefile (xtrace): Likewise.
