The drive letter issue is the real problem.   Most windows programs accept 
POSIX slash paths.   But they do not know about /cygdrive/c or /c/.  They
only know c:/.   But creating a patch that only allows the drive letter and
not \ MS-DOS paths would be much more work since the work of having both
\ and / paths supported is already done.
