3) Paths. This is a HUGE problem because you can't assume that your
Windows customers are interested in using a Unix style of work flow.
MinGW supports regular Windows paths without the whole /cygdrive/
system. If you have a pure Windows app interacting with Cygwin tools
(take Eclipse for example) you wind up putting an awful lot of cruft in
to deal with pathname conversion. You can even get problems when your
debug information in your binary has either Cygwin or Windows paths.
Again, AFAIK, gdb works with native paths. If it doesn't then getting
it to work with windows paths seems like a lot less pain that getting
it to be 100% functional in native windows.
