XFree86-f*.sh: umount, cygpath, mount
Note: the above script should also check that the directory is
already mounted in the correct mode instead of unmounting and
remounting it all the time.
XFree86-lib.sh: mkdir, test?, tar, rm, ln
XFree86-prog.sh: touch, ln
XFree86-xserv.sh: ln
fontconfig.sh: dirname, basename, diff, cp, mkdir
Note: this one also uses bash syntax. Moreover, it requires things
like "diff" and "dirname"/"basename" to run, but neither "diffutils"
nor "sh-utils" are in the "requires" clause of "fontconfig".
