Surely not!

The standard says:

7.12.8.4 The tgamma functions
Synopsis
1 #include <math.h>
double tgamma(double x);
float tgammaf(float x);
long double tgammal(long double x);
Description
2 The tgamma functions compute the gamma function of x. A domain error 
or pole error may occur if x is a negative integer or zero.

Read with me:

MAY occur!

Maybe not. This standard is so worded that you can do anything with it!

So, if I define the tgamma function for negative integers as specified 
in that paper I am still standard conforming.

Besides, if the user gives negative numbers it is because he wants the 
definition specified in that paper. The standard  doesn't even specify 
the error return!
