A number of these sources are indeed shared (some compiler sources
are used by the library and/or some tools) and moving them is not
straightforward.
We are however planning to rearrange things in this area as well and
much appreciate your suggestions.
The set of "gcc interface" files is easier to handle and moving it
would really help our transition to svn in the short term, so we
decided to start there.
The two changes in the common infrastructure we have are:
1) Add a new "gcc_subdir" variable in config-lang.in. When set, configure
looks for a complete config-lang.in, makefile fragments (Make-lang.in),
lang tree files, ... in $(srcdir)/<lang_name>/<gcc_subdir>. When not
set it looks in $(srcdir)/<lang_name> as usual.
2) adjust gengtype not to reflect the extra subdir in the names of
the files it generates.
This is probably not technically mandatory. We just thought it
would be nice to leave the gt filenames untouched (only dependant on
the language name).
The patches are short and we would be happy to submit them if the
approach is deemed acceptable.

We would be very happy not to have to maintain this one any more :)
We're not quite there yet, unfortunately, but keep this as another
target improvement in mind.

Indeed. Thanks much for your feedback,
