I should've made that clear, sorry. This patch is just a much needed fix
for the current code to *not* munge pathnames unnecessarily when these
come from the environment variables; the patch to actually handle 
user-supplied names on the command line will be a separate patch coming
soon (hopefully before the freeze!). And that's the reason for my 
statement:

I'd like to get this in first before trying to add Cygwin specific code to
the language driver/cpp that the EGCS maintainers may object to.

With this patch, as long as you use POSIX pathnames, the compiler will
too. A small, but important, step in the right direction.
