[Patch, fortran, committed] Use ISO C remove() instead of unlink()

[Janne Blomqvist <blomqvist dot janne at gmail dot com>]

Hi,

when removing a file we can instead use the remove() function
specified in ISO C instead of unlink(), as found in POSIX, Windows and
probably other systems as well. Thus giving us a bit better guarantee
about the provided semantics, which header file it's found in etc.

Committed to trunk as obvious.
