I tried.  Many failures, unrelated to fullname, led me to
believe that configuration was not considered as supported
by the mi testsuite.

Also, in my tests at least, the fullname paths from stack frames
all come back as /cygdrive/<drive_letter>/..., so the simplistic
regex would suffice.

This is a good idea, but as the complexity of the regex
increases it becomes more compelling to do an exact check.
Calculate what the absolute path to the source file should
be and compare that with the fullname attribute.  However,
I'm not volunteering to do that.  ;)  It's easy to overblow
the testing for what amounts to a five line code change.
