hi folks, we have a small compatible extension to lgamma, a standard C function. we provide the sign of gamma(x) result in signgam, in a global.
we also have a reentry safe version, lgamma_r, where signgam is passed as an argument. because this is a standard C function, I assume the compiler is completely free to replace it with a standard implementation, so using our extension is unsafe even on netbsd. i think it would be reasonable to get rid of the extension (modifying signgam) in the next shlib major bump for this reason. thoughts? secondary: would we want to keep lgamma_r then?
