Well, in the past... ;-) > The suggested versions > are known to work and have been thoroughly tested, which might not be true > of the latest versions. Sure. But note that this is not (or no longer) true for at least GMP 4.3.2, assuming "works" includes "the library's test suite passes [when compiled] with GCC". I.e., GMP 4.3.2's test suite contains a subtle bug (fixed long ago, in all later versions) that will cause a single test (t-scan) to fail when compiled with GCC 4.8.0 and any later version; it only incidentally doesn't show up with earlier ones. While the bug doesn't affect the library code or GCC itself, it is annoying to users building GCC as well, as most won't know until they report it to gmp-bugs, which happens pretty often. (In fact, the error message of course asks them to do so. And people are encouraged to run 'make check'.)
