[Openal-devel] MP3 format token value

Huh? The OpenAL 1.1 spec clearly states that extension names are
case-insensitve, so it has nothing to do with Unix, autoconf, etc., it
is just a convention one has to follow when parsing the extension string
by hand. al(c)IsExtensionPresent do this automatically. But perhaps I've
missed the point here...
And I don't understand the problems with Torque (I don't have the
sources): Do they ship their own OpenAL? Anyway, relying on case in
filenames is a good recipe to ensure non-portability, as there are quite
a few case-insensitive filesystems out there, even if some of them are
case-preserving (e.g. Apple's HFS+, Window's NTFS, etc.). :-)
Cheers,
S.
