Actually I had replaced the md3, md4, iqm pointers with a union in my
development code, but that would mean to change the md3/md4 code too and using
the md4 pointer seemed a bit hackish, as the variable name implies it is used
for md4 only.

If you're going to update the MD3/MD4 loaders anyway shouldn't we at least
rename the md4 pointer to "modelData" or something ?
