Silly, silly, silly, stupid, forgetful me. I forgot that current versions 
of gcc are broken in cygwin. 2.95.2 is the last version that seems to build 
properly. Here's the output from the current sources.

So it isn't possible to develop for thumb inside cygwin, unless you're 
writing in 100% assembler.
