Okay great, thanks.  I'll wait for comments then install.

Yes, will do.

I don't mean to overload you, :-) but now that we've resolved the initial
mpfr-2.3.0 issue, do you have any thoughts on the remaining related

Evaluate Bessel Y using MPFR:

Evaluate remquo/remainder/drem using MPFR (depends on the above):

Add reentrant lgamma_r builtin (no dependencies):

Evaluate reentrant lgamma_r using MPFR (depends on the above):

Show MPFR version in "gcc -v" (no dependencies):

(I'm still reworking the plain c99 lgamma patch for the signgam issue, so
consider that one withdrawn.)
