Description: Fortran module search directories included ../src and
../../fortran/src directories; this was defined in
acsite.m4 file in order for fortran and HL fortran tests
to compile. Those flags were included in h5fc and h5pfc scripts.
Solution: Removed those directories from acsite.m4 file and updated
Makefile.in files.
Platforms tested: sequential on arabica and parallel on copper
including HL Fortran
Misc. update:
