Allegro mostly uses X11 libraries which dont have m4 macros, iirc, and 
normal system libraries that every unix installation should have anyway. 
It could take advantage of the esd.m4, alsa.m4, and maybe other m4 
macros that are used to build the modules. Currently someone hardcoded 
aclocal.m4 to test for all the modules, but most of these libraries( 
well I can only account for esd and alsa ) have their own m4 macros in 
/usr/share/aclocal. I cant say its "better" to use these macros, but 
thats what they are there for.

Rather than have people who want to use Allegro hack together their own 
m4 macro just like Allegro has for esd and alsa, it would be better to 
supply an m4 macro. God knows its hard enough to write one of these 
things yourself.
