A similar issue potentially arises for OpenMP's Fortran libraries under
finclude/, i.e. omp_lib.h, omp_lib.f90, omp_lib.mod, omp_lib_kinds.mod.

Recall that the module files (.mod) are not preprocessed - and the .h files are
not if one uses "include 'omp_lib'" (instead of "#include")

However, I think for currently used type there should be no problem (with
all/most targets).
