Oh dear... :) If you look through the archive of this list, you'll see that 
I struggled with this one for a long time too.

I can email you my Win32 toolchain as a zipfile (just unzip it to 
cygwin/tools) if you want. It is an arm-elf toolchain based around gcc 
2.95.2 (so it does NOT support Thumb). At this time I do not believe there 
is any way to get gcc's thumb support working under cygwin; I tried for 
months (off and on) and although it's possible eventually to build 
something (by manually cutting out bits of source files that don't compile 
properly), the result is non-functional.

I strongly urge you to move to Linux, which was the advice I was given very 
early on here on this list. I tried and tried to get Win32 working right, 
but I gave up last week sometime. Although it is very inconvenient to some 
people (including me) to have to dual-boot multiple OSs, Linux is by far 
easier to work with for this stuff. It's also much faster; it seems that 
every time you run a cygwin binary it has to reload a bunch of DLLs or 
something.
