Configure failed, and configure.in as a comment that says "TODO" to do 
exactly as you said.  I considered making the change, but decided it was 
a non-issue at the moment.

There are makefiles available I found through googling, as I said, 
though, I ran out of time.  I intend to screw with it again later this 
afternoon/evening, after I've caught up at work from being sick.  I'll 
definitely have to get the CVS branch you're talking about.  I'd really 
like to see audacity compile under cygwin, but after I get it compiling 
under cygwin, I intend to see if I can get audacity to compile under 
Linux cross-compiling for windows.  Ultimately, if it works out to be 
able to generate windows builds reliably, you might be able to use 
sourceforge's compiler farm to do it.  Of course, I'm just doing it for 
fun, I just like to find practical applications for stuff.  :)

Hmm, in response to Bill Eldridge's post, cygwin comes with the MingW 
header files and stuff.  It's what gets used when you compile wxWindows 
under cygwin.  I had expected (hoped, even) that wxWindows would compile 
in gtk under cygwin, and was mildly impressed when it didn't.  wxWindows 
binaries compiled under cygwin also do not depend on the cygwin runtime 
dll, so if I can get Audacity to compile (and provide appropriate 
patches to be included, and possible offer some long-term maintenance) 
then Audacity will be independent of Visual C++, which is a Good Thing, 
I think.  :)  (This is actually part of my effort to create a CD 
distribution; first I need a reliable way to build the stuff, next is 
figuring out how to use Mozilla's perl script for building installers)
