Hi,Commit 235763 removed support for versions of MPFR below 3.1.0 which have a flat directory structure, however it did not introduce any safety check for such an unhandled library version present in the tree. Consequently the system-installed version is silently chosen, which if too old, causes a confusing configuration failure in mpc/ stating a misleading version requirement: checking for MPFR... yes checking for recent GMP... yes checking for recent MPFR... no configure: error: MPFR version >= 2.4.2 required make[1]: *** [configure-mpc] Error 1 I propose the check below to make people's life just a little bit easier and indicate right away that an incorrect version of MPFR has been found in the source tree. This is especially helpful when you just sync your build tree from upstream and may easily miss the updated requirement. I carefully chose to use "handled" rather than "supported" in the message as the commit referred clearly indicates you are on your own with versions of the libraries different from those stated in `download_prerequisites'. 2016-08-12 Maciej W.
