1) The documented way to specify this is to set FPICFLAGS in config.site:
see the example in R-admin for the PG compilers. When you tried that,
what went wrong?
2) It seems strange to specify this for the Fortran compiler and not the C
or C++ compiler.
3) You have suggested the change to a section for all OSes. Do you know
for sure that all compilers called 'ifort' on all OSes need the -fPIC
flag? Or is it really just for Linux (and AFAICS, just x86_64 Linux, as
i386 Linux seems to work with icc/ifort without it).
