[R-SIG-Mac] native binary for macintel machine

[Jan de Leeuw]

I managed to build a native binary (Mach-O executable i386) for the  
MacIntel machine
on a MacIntel machine, using the bundled gcc and the (beta) Intel  
fortran compiler. This
is a framework build with aqua support -- the quartz device works  
fine, so does the X11
and tcl/tk interaction. I have to do most of the links manually  
because configure/make
does not find the correct Intel dylibs.

I have NOT been able to compile a native gfortran from the apple cvs  
(low priority for apple)
and i have NOT been able to build R using the intel C and fortran  
compilers (mostly
configure problems).
