Hi all. Thanks for your help with cygpath (I *did* look in 
the FAQ, I just didn't know what to look for). :)

cygpath *seems* to be doing the right thing (it's hard
to tell), but there is some sort of problem with
backslashes. I have a rule like this:

%.obj : %.cpp
	$(CC) $(CPPFLAGS) $(shell cygpath -w $<)

The idea is that this will invoke sh.exe with something like:

 /c/VC98/bin/cl.exe /Fo:globref.obj c:\r7\jni\src\globref.cpp

But instead it seems to do:

 /c/VC98/bin/cl.exe /Fo:globref.obj c:r7jnisrcglobref.cpp

which causes the compiler to bomb out with:

 fatal error C1083: Cannot open source file: 'c:r7jnisrcglobref.cpp': No
such file or  directory

I figured I need to escape the backslashes before passing them
to a shell command. So I tried things like:

%.obj : %.cpp
	$(CC) $(CPPFLAGS) $(subst,\\,\\\\,$(shell cygpath -w $<))

but the subst function seems to just return an empty string (this
happens even when I use something without backslashes,
like $(subst,a,b,whatever).

Has anyone run into this?

Thanks,
	c
