`make depend' is broken in the CVS sources.  I've only tested it when
using a build directory which is different from the source directory,
but frankly it looks broken anyhow.

This is what I get:

make -C backend depend
make[1]: Entering directory `/home/ian/pgsql-objdir/src/backend'
for i in access bootstrap catalog parser commands executor lib libpq main nodes optimizer port postmaster regex rewrite storage tcop utils; do make -C $i depend; done
make[2]: Entering directory `/home/ian/pgsql-objdir/src/backend/access'

make[3]: Entering directory `/home/ian/pgsql-objdir/src/backend/access/common'

gcc: *.c: No such file or directory
gcc: No input files
make[3]: *** [depend] Error 1

make[3]: Leaving directory `/home/ian/pgsql-objdir/src/backend/access/common'

make[2]: Leaving directory `/home/ian/pgsql-objdir/src/backend/access'
make[2]: Entering directory `/home/ian/pgsql-objdir/src/backend/bootstrap'

gcc: *.c: No such file or directory
gcc: No input files
make[2]: *** [depend] Error 1
make[2]: *** Deleting file `depend'

etc.

Making this change to src/backend/access/common/Makefile fixes the
first error:

Index: Makefile

I can submit a patch to make a similar change to all Makefiles.
Before I do, is `make depend' still supported?  Is there a better way?

Ian
