[R-SIG-Mac] New compilers for Xcode 2.2 (universal gfortran and gcc 4.0.3 for Intel Macs)

[Simon Urbanek]

I have uploaded a new set of compilers today - the links and details  
are on the Wiki:
http://wiki.urbanek.info/index.cgi?TigerGCC

This is the first time gfortran is universal (i.e. runs on both ppc  
and i686) and uses Apple's driver, i.e. you can build fat binaries  
with it (e.g. -arch ppc -arch ppc64). Intel gfortran target works  
only with the gcc 4.0.3 and only on Intel Macs.

Cheers,
Simon
