hmm, too bad.

anyhow, older versions of zexy included a dummy replacement for
_get_output_format(), but this has been dropped because it was no longer
needed for "newer" versions of mingw.

which suggests that the solution is to update your MinGW installatin
(though i don't know what version you would need).

a workaround might be to just patch rawprint.c to enable the fix
(rawprint.c:29)
