I like this options, which is similar to how NAG
handles their modules.  NAG places everything
in /usr/local/lib/NAGWare.

I must admit I don't understand why you need to install
omp_lib.f90 and omp_lib.h.  I would have thought that all
you need is omp_lib.o, omp_lib.mod, and omp_lib_kinds.mod.
Shouldn't -fopenmp simply add omp_lib.o to the link command
and USE OMP_LIB look for a omp_lib.mod?

BTW, what are your merge plans once 4.1 is branched?  I can
help with limited code review and testing on weekends.
