Actually, the name "gamma" has been used for functions that
computed both Gamma and log_of_Gamma.  (Not at the same time!)
On most systems I have used, "gamma" computed (an approximation
to) the log of Gamma of its argument ("lgamma" is the Standard
C name for such a function, "tgamma" being used for the not-log
version; we decided not to use the name "gamma" for either,
because of the conflict with some of the existing practice).
