I guess this happens because these functions are defined as AL_INLINE
in include/allegro/aintvga.h.  For optimized library these functions
are inlined, but for debugging version they are treated as extern.
Other functions, defined with AL_INLINE in "allegro.h" and
"allegro/aintern.h" are also compiled into library as normal functions
in src/inline.c, but these VGA/MODEX functions defined in
include/allegro/aintvga.h are not included as normal functions.
