OK, just to summarize for everyone here, so when binutils is installed in 6.16, from that point forward, the ld the system is using will link what is being built to libraries in /usr/lib rather than /tools/lib. And that means that when MPFR is built, its configure script should not be able to even build anything linked against libquadmath because that does not exist yet in /usr/lib. Correct? In the mpfr-4.0.1 source tree, I did a: grep -r MPFR_LIBQUADMATH * I don't see any effect from the detection of the availability of libquadmath other than to add -lquadmath to the LD flags - nothing that would suggest code pathways being altered or tests being selected or otherwise changed. They may have just put the detection in there for completeness, in case they ever do want to use libquadmath's features, if, and only if, it is available on the system. Well, maybe the issue John encountered *is* the whole point of it - that the tests should error out if they can be built linked against lquadmath, but not successfully executed - that they wanted to test for that possibility of things going wrong.
