No idea. Maybe something to add a configure test for ?
I have Linux 2.2.10, glibc 2.[01] (Can't remember what exactly).
I think it's a glibc thing IRRC.

There is a define ALLEGRO_NO_STD_HEADERS, which might be used

Ahem. I had done some define trickery to detect if a specific
version was defined, and define the generic version if not. It
should work, unless it's rotted enough :)
