[Bug testsuite/37623] New: builtin-math-4 tests fail

[tim dot vanholder at anubex dot com]

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.

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.

See the comment at the beginning of the testcase.  Moreover, configure should
have reported that the version of MPFR is not optimal.
