Follow-up Comment #2, bug #31753 (project octave):
John, your're right, the header file needs _REENTRANT to be defined in order
to make the declarations available!
I built octave with gcc version 4.2.1 (Apple Inc. build 5664).
Here's the according snippet of math.h:
#ifdef _REENTRANT
#include <AvailabilityMacros.h>
// Available on OS X 10.6 and later.
extern float lgammaf_r ( float, int * )
AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER;
extern double lgamma_r ( double, int * )
AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER;
extern long double lgammal_r ( long double, int * )
AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER;
#endif /* _REENTRANT */
