Looks like your link command is mixing libraries from different
versions of the compiler (why would i686-pc-cygwin gcc be looking in
/usr/lib/mingw - maybe you're using -mno-cygwin and need a newer mingw
library?). How about posting the output from your failing link command
with a -v option to list the exact commands that gcc is issuing during
the link process. Having multiple versions of the compiler installed
can be a bit treacherous, and -v will show you exactly what it's doing
and where it's looking.

Are you attempting to use the cygwin compiler to build a mingw
compiler? This is a cross-compile and I seem to remember it was pretty
hard to get it working this way. I found it much easier to use a
native mingw compiler to build gcc 3.2 mingw - from my experience the
most important thing is to ensure you know what compiler is being used
during the build process. I just renamed all the cygwin compiler
binaries to prevent the wrong versions being accessible during the
build.
