Compiling R for Solaris 10 Intel

That is a rather old compiler.  R on Intel Solaris works better with the 
(free) Sun compilers, but I have built R on x86 Solaris with gcc 4.0.x 
(I think 4.0.3): I have never made a 64-bit build work with gcc.

One thing to make sure is that the compiler was actually built for
Solaris 10 (and not say 9).

I have to say that most reports we have on non-native compilers on OSes
boil down to compiler bugs, and the first step is turn all optimization 
off and see if the problem disappears.
