Clean build from a source tree that was the result of svn switching to the 4.3.2 release tag (was previously a 4.3.0 release I think). make check reports a handful of errors; I'm logging each separately once I determine the likely cause. The builtin-math-4.c test (8 flavours) from gcc.dg fails. Lots of linker errors for link_error in the log (which looks like the expected failure type for the testcase). Notable is all flavours except the -O0 one have linker errors other than the intentional link_error ones. In particular, the gamma_r, gammal_r, gammaf_r end up being undefined, so it looks like some not-always-builtin math routines are also included in the test. I'll attach the error list for the test that uses -g, as there the line numbers of the link errors are included.

That probably means you have too old mpfr.
> That probably means you have too old mpfr. Yes, I just upgraded from 2.2.x to 2.3.1 on Solaris and the failure vanished.
Then perhaps either configure should reject the too-old version, or the testcase should detect this situation and either skip the tests in question and/or report that MPFR is too old. The situation as it stands is not very helpful.
