  11 # Revision 1.1  2001/07/07 16:51:04  bergers
  12 # Libgcc1 as needed for gcc for m68000 targets since the compiler itself does not know the code for certain 32 bit operations that are not part of the m68000 instruction set. Found this library on http://rpmfind.net/pub/CROSS-68000. I contacted the author (Daniel Veillard) and he said it is alright for us to use the code.
