[Rd] problem building R-patched on x86-64 with PGI 6.1

[Liaw, Andy]

Thanks to Brian, I can now get PGI 6.1 to build R-devel 
(2006-03-13 r37533) and pass make check-all, using the 
config flags I showed in my original post.  I will try
to re-build with optimizing flags, and report back if I
run into problems there.

Best,
Andy
