Right now there's no support for building a JAWS binary.
From my browsing of the source, it looks like to do so, you:
1) #define JAWS for the build
2) use jaws.rc instead of winboard.rc
Is that correct?
We need to remove item 2 so that it's automatic if JAWS is defined. I
can do that, but there's a LOT of common code that should be shared, so
it would make sense to clean up the rc file at this time. [otherwise,
you make a change to some odd dialog/menu/accelerator, and it only
happens for non-jaws binaries]
