I applied your patch here (http://hg.savannah.gnu.org/hgweb/octave/rev/f10b7a578e2c). I also added some tests in mappers.cc for the new return values for exceptional inputs. This will all be part of the 3.8 release due in a few weeks. Thanks for contributing.

gamma(x) returns NaN for x = negative integer or -Inf
Returns -Inf for x = -0 or if result overflows and is negative
Both of these are the same return values as tgamma() in <math.h>
