Well, there's a bit in the attached plugins.m4 (in case you're
interested) that walks the directory looking for plug.in files, at which
point it includes them.
The exact code that calls it is:
AC_DEFUN([_DRIZZLE_INCLUDE_LIST],[
ifelse([$1], [], [], [
m4_define([__mysql_include__],[$1])
builtin([include],$1)
m4_undefine([__mysql_include__])
_DRIZZLE_INCLUDE_LIST(m4_shift($@))
drizzle_plugin_files="\${top_srcdir}/$1 ${drizzle_plugin_files}"
])
])
This works, although it doesn't register $1 into am__aclocal_m4_deps.
However, if I change builtin([include],$1) to m4_include($1), I get:
aclocal-1.10: m4/plugins.m4:810: file `$1' does not exist
sinclude() works in this context, but gets me the weird extra rebuilds.
BUT
m4_sinclude() works like sinclude() with the same problem.
I ran aclocal with --verbose, and at the end I got:
aclocal-1.10: reading aclocal.m4
aclocal-1.10: aclocal.m4 unchanged
As far as I can see - make is picking up the fact that
plugin/md5/plug.in changed, and is triggering the aclocal run, but in
this case, plug.in didn't produce any aclocal changes, so the cache
stuff that checks to see if any changes happend to prevent a needless
configure run doesn't update aclocal. But this means, since we have a
recursive subdir thing, that it performs the aclocal run in every dir,
every time we make from that point on.
So it seems like the extra configure in this case might actually be less
work.

Adding --force to ACLOCAL_AMFLAGS makes it work (with m4_sinclude, not
with m4_include) Are there downsides to doing that? (other than running
configure needlessly I suppose)

Thanks for the help!
