Ed Schouten b6cd89849e Don't let tgammal() modify signgam. Only lgamma*() should modify it.
Letting tgammal() modify signgam has two disadvantages:

- It breaks valid code that assumes that the value of signgam is not
  clobbered by calls to tgammal().
- It makes this function depend on the presence of signgam. signgam is
  an X/Open System Interface. It is not part of the C standard.
