source: trunk/base/aclocal.m4 @ 52324

Last change on this file since 52324 was 52324, checked in by toby@…, 11 years ago

Merge universal-sanity branch. Changes are relatively straightforward, although somewhat risky:

  • remove universal_sysroot/universal_target options
  • hardcode the 10.4u SDK for Tiger/PPC, only platform that needs it
  • Property svn:eol-style set to native
  • Property svn:keywords set to Id
