I added a new file in bindings/f95 called plflt.txt (I picked .txt to
make sure it would not conflict with a traditional source file, however,
a better name might be better). Then I applied the attached patch to
bindings/f95/CMakeLists.txt. I was conservative and restricted it to
WIN32, however, there is no reason it should not apply to all
platforms. There probably is a better way to get it to work, so
applying this patch might not be the best way forward.
