I assume you mean erand48_r, there, because erand48 is pretty standard.

Maybe.  But if that's the approach we want to use, let's just call it
pg_erand48 in the code, and dispense with the alias macros as well as
all vestiges of configure support.

BTW, as far as the original plan of using random_r is concerned, how
did you manage to not run into this?

I just wasted half an hour on that stupidity in an unrelated context...
