[Rd] qbeta function (FYI, compiler bug)

[Morten Welinder]

Hi there,

this is just to let you know that the qbeta function, which was
copied from R into Gnumeric, has been confirmed to be miscompiled
by gcc 2.96 on Linux.  (That's Red Hat's compiler.)

This shows by qbeta(0.025,4,0.5) ending up taking the wrong
branch of "if (alpha <= 0.5)".

We compile things in a different context, so this may or may not
affect you.  The qbeta function was taken from R 0.64.
