Sorry for the slow reply, got lost in my inbox. Perhaps I get too much
mail...

I'm not entirely sure what VPATH is. Apparently some way for make to
find dependencies which are in non-obvious places, according to the
all-knowing google. I've never consciously set it up, but maybe
automake does this automagically for non-recursive setups? Maybe I
should explain some more about my build system.
My directory tree is something like:
/
/configure.ac
/Makefile.am
/INSTALL
/README
/ChangeLog
/<etc.>
/tests
/tests/Makefile.am
/src/Makefile.am
/src/parse/Inc.am
/src/ast/Inc.am
[. . .]
The toplevel automakefile (`/Makefile.am', above) is simply a recursive
make call via SUBDIRS, into both `/src' and `/tests'. The automakefile
in /src (`/src/Makefile.am') is a NONrecursive make which has lines
like
include $(srcdir)/parse/Inc.am
in it. I'm running `make dist' from the `/' given above.

Thanks, I was unaware that extension was possible.

Done. I also tried removing it from the `include' statements I
mentioned above. While its working fine in terms of building the
software, I'm still getting the same `make dist' error (well, now
"scan.ll" is replaced by "scan.lpp", but same deal).
Thanks for your help / advice!
