Hello List,
I have just noticed a weird behaviour for gsl_isinf (GSL 1.11):
gsl_isinf(GSL_NEGINF) give -1 (as expected) on some of my computers,
whereas it gives +1 on others: my computer are amd64 Debian boxes (Etch based
and Lenny):
Amazingly, it seems that this feature is not well tested.
hth,
Jerome
