[Rd] problems compiling R on AIX5.1

[Prof Brian Ripley]

Thank you for the success report!

AFAIK macros FC and CCFLAGS are not used, and it is CXX and not CCC for 
the C++ compiler.

We will alter foreign's names to avoid the conflicts.

--disable-shared is the default: it refers to *building* shared libraries 
(libR.so in R's case).
