2003-07-11 Phil Edwards <pme@gcc.gnu.org> * acinclude.m4 (GLIBCC_ENABLE_SYMVERS): Tweak comments. Add warning messages if the environment cannot support symbol versioning. (port_specific_symbol_file): It's plural, add an 's' on the end. * configure.host: Likewise. * src/Makefile.am: Likewise. * config/linker-map.gnu: Remove one semicolon, heh. * scripts/extract_symvers: Don't assume useful 'export' syntax. Set LANG as well as LC_ALL for possibly-broken sort(1)s. * aclocal.m4, configure, src/Makefile.in: Regenerated. From-SVN: r69212
