This is true. depends needs to refer to .obj files under MSW, instead of
.o files. After I sent that last message, I thought "wait a minute,
didn't Roy say .obj instead of .o?"

But that won't work, because depends needs to include dependencies that
can't be known at the time extconf.rb runs, such as button.cpp depending
on window.h. This is because of the extra process for .t files.

So I think I can just modify my depends file to include a second copy of
itself, replacing all the .o with .obj. The MSW version will ignore all
the .o entries, and the Linux version will ignore all the .obj entries.

Roy: You can try this yourself, for now, by editing 'depends', and just
replacing all '.o' with '.obj'. But you'll have to start with a fresh
cvs checkout (aside from this change) in order to really test that it
can build all the .t files correctly.
