Well, I'm not an interposing expert at all, so I'm not sure how other linkers 
will threat them, I'm not even sure if this works as intended on Linux 
(although I hope so), but I'm pretty sure it won't work that well with 
the -Bdirect patches (not like this is the first X library with this 
problem :) ).

I was thinking of using the AC_CHECK_FUNCS method myself, but this means 
having about 6 lines for every function, as you cannot use preprocessor 
macros expansion to do the job (#if* in macros is not allowed)..
The only way I can think to do this "cleanly" is to use an sh script that 
generates the C code, but it's kinda strange that approach, too. Or maybe 
using the Makefile itself and generate a series of .c files with the stubs 
for every function. Both these solutions are kinda complicated, I'd still 
prefer the current solutions.

Yep, thought so, I usually do that, but this time I wasn't really sure of its 
completeness.
