hmm, these are already guarded by #ifdef OSG_GLENUM_NEQ_UINT32 which in
OSGConfig.h is set like this:
# include <AvailabilityMacros.h>
# if !defined(MAC_OS_X_VERSION_10_5) || (MAC_OS_X_VERSION_MAX_ALLOWED <
MAC_OS_X_VERSION_10_5)
# define OSG_GLENUM_NEQ_UINT32
# endif
Does your application include OSGConfig.h as it's first OpenSG header?
Have you set any of the defines that influence the definition of
OSG_GLENUM_NEQ_UINT32 above?

yes, that is how we use OpenSG in our projects too.
