There are a whole bunch of issues with this tarball.
1) It is missing the two files dos2unix/dos2unix.1 and
unix2dos/unix2dos.1. They need to be listed in an
EXTRA_DIST= line in Makefile.am.
2) The error message printed when windres can't be
found doesn't display and instead configure prints out
an error mesage.
3) drmingw is missing a bunch of headers that don't
appear to be in the CVS tree either. Also it hasn't
been updated to match the current definitions of the PE
structures in WINNT.H.
In addition to the above problems, it doesn't be build
on 64 bit systems.
I've attached a patch that fixes the first two problems
and allows the portable programs to be built on 64 bit
It also adds configuration options to allow the build
of the non-portable programs drmingw, redir and
res2coff to be disabled.
