Merged from gcc-3_0-branch: 2001-07-30 Jeff Sturm <jsturm@one-pont.com> * ltcf-c.sh: Use $objext, not $ac_objext. 2001-07-27 Mark Kettenis <kettenis@gnu.org> * ltcf-cxx.sh: Add support for GNU. 2001-07-22 Timothy Wall <twall@redhat.com> * ltcf-c.sh: Don't disable shared libraries for AIX5/IA64. Preserve default settings if using GNU tools with that configuration. * ltcf-cxx.sh: Ditto. * ltcf-gcj.sh: Ditto. 2001-07-21 Michael Chastain <chastain@redhat.com> * ltconfig: Set max_cmd_len to a maximum of 512Kb, as it seems some HPUX 11.0 systems have trouble with 1MB. Mark as gcc-local. * ltmain.sh: Mark as gcc-local. From-SVN: r45341
