I think we might be able to do better:
--Makefile--
subdir = src/bin/psql
include ../../Makefile.global
--Makefile.global--
top_srcdir = @top_srcdir@ # provided by autoconf
srcdir = $(top_srcdir)/subdir
VPATH = $(srcdir)
...
--Makefile cont.--
# build stuff
That way you can build in any directory.
Well, that makes things a lot simpler. Then we really don't need any *.in
files at all except for a select few. We'd just dump all @FOO@ things into
Makefile.global.
Of course I somehow have to hack up AC_PROG_INSTALL so it doesn't give a
relative path to install-sh, but that can be done.
