hi, i'm trying to compile a little proggy in g++
but at the begginning,after the inclusion of

#include <tgl/gla.h>

the compiler tells me :

gla.h:15 error expected unqualified-id before 'int'

but in gla.h at the 15 line there is only

int GLAInitializeContextWindowed(GLContext *context, void *w);

any tips?
