When building for mingw in cygwin you should also configure with --build=mingw32 and 
--host=mingw32. But that still won't address those errors you get for building gcc. For those, 
see PR#14316:
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14316>
There's a patch in that bug report that should help.

But there was a recent post to the list that pointed to a place where you can get prebuilt 
binaries for a SH toolchain:
<http://gcc.gnu.org/ml/gcc/2004-07/msg01313.html>
