Cygwin runs the test ok these days, but not MSYS/MinGW.
MSYS still stumbles on carriageret and the only workaround I could
think of is to check if the current test is carriageret and
skip instead of fail if $test_string is empty in that case.
But that's quite ugly, and doesn't really bring us much as the test
falls over again on dosdrive aka 'a:'. On MSYS, "mkdir ./a:" creates
the directory "a", w/o the trailing colon. Marvelous.
So, next (ugly as hell) thing to do is to try to create a dir with
only a colon if there is any colon in $test_string and skip if that
fails.
If you're not busy puking all over the place after reading the
patch, you might be able to convince me to write a commit message
for it...
The test no longer "fatals" on MSYS/MingW with these changes
(instspc: exit 0).
Cheers,
Peter
