that's the way the core autoconf wants it: use an *.in file.

I did specifically made up the _create_prefix_ macro to *easily*
get the results of _HAVE_ and _SIZE_ checks into an installable
file. Otherwise, a selected series has to be picked and re-SUBST-ed
for being then picked up in a manually-written pkg-config.h.in
as opposed to the automatically-generated config.h.in

well, may be an automatically generated pkg-config.h.in might
help - and indeed, similar things have been implemented in a
matter close by of installable config.h files: the automatic
creation of pkgconfig scripts (a.k.a. glib-config sdl-config
bin-commands), which shall pick up most parts from the other
configure macros.

For the latter, the corresponding macros in the ac-archive.sf.net
might be of help in looking at possible implementation sides of
handling selectable config.h mechanisms. There are more macros
that can help library makers in getting things done where the
core autoconf system has just rock functionality shipped along.

have fun, guido
