On cygwin you don't need to do this. However you still need the binutils, run time library, etc. You should use the 'one-pass' procedure as described in section 4.2 of the FAQ. Another alternative is to download the pre-compiled binaries from http://www.objsw.com , they won't be able to handle long file names under NT (since they're DOS applications) but everything else you need is there. > > I'm alittle at a loss.
