source: branches/stable/mondo/src/mondoarchive/mondoarchive.c @ 1377

Last change on this file since 1377 was 1377, checked in by bruno, 12 years ago
  • ARCH removed from configure.in as useless
  • addition of get_uname_m (to give the underlying arch)
  • get_architecture now returns correctly the built arch used (including x86_64)
  • IA32 is defined for both i386 and x86_64. An additional vdefine X86_64 is also setup for tha later arch.
  • Property svn:keywords set to Id
