that wouldn't be easy to achieve.

There are two possible setups:

1) Either the subpackages are autonomous, usually not under your control...

Then let each package do what it needs to configure itself, including
its own aclocal.m4.

2) ... or the subpackages are not _that_ autonomous.

Than it makes more sense to create one big configure, which checks for
all necessary things and then generates all necessary makefiles and such. 

If there are checks which are needed only for one "subpackage", you can
put that parts of configure.ac to subpackage/config_frag and use
m4_include to include that into the main configure.ac.

The file freetype2.m4 came with freetype.

This bug was fixed in freetype 2.1.6.

Have a nice day,
