Attached is a patch to the current mob which allows cygwin to be correctly recognized and tcc to be built. Unfortunately, the rest of the work is fixing the system includes for cygwin which I haven't been able to figure out.
I request that this commit be reviewed and applied as having it part of the planned tcc release will increase chances of having things work on cygwin eventually. Thanks much, Chris
