Subject: gengtype and automatically generated files

Hi! I'm attempting to do something that may not have been done before,
so I'm looking for advice, or a pointer to where, in fact, it has been
done before. :)
I'm automatically generating a back-end header file that declares some
structures that include trees, and a bunch of global variables that are
also trees. I've marked everything up appropriately, but I also need to
teach the garbage collector that this file exists.
Most back-end files are automatically scanned by gengtype. Per the
documentation, anything that isn't handled automatically needs to be
added to target_gtfiles in config.gcc. However, I can't come up with a
syntax for describing a file in the gcc/ build subdirectory. Some
places in config.gcc allow "./filename" as shorthand for "filename"
being in the current build directory, but that doesn't seem to work for
adding something to gtyp-input.list.
Any recommendations on what I should do next? At the moment it looks
like I might have to hack on gengtype to invent a way to scan a file in
the build directory, but I have a mild amount of hope that someone has
solved this before. Thanks for any help!
Bill
