Re: [PING][PATCH]: Warn that mpfr-2.2.0 is buggy when configuring

2006-12-17 Kaveh R. Ghazi <>

* Warn that MPFR 2.2.0 is buggy.

* configure: Regenerate.

PING for configure patch.

I disagree with Joe on this: I think that we should not accept MPFR 2.2.1 because, by the time GCC 4.3 is out, most distros will have upgraded to the new version. The comparison with binutils is "unfair" because gcc's configure script has code to detect some known binutils deficiencies or bugs, and will omit features in case the detected version is buggy. So, unless we do the same for MPFR (not in GCC's configure script: we may just disable MPFR constant folding if the version is 2.2.0), there is no reason to allow a buggy version of a library that GCC has not ever required (at least for the C/C++ front-ends).

The patch is ok for the 4.2 branch, modulo changing "buggy version" with "yes, buggy but acceptable", because we don't use the buggy features in that branch.

For mainline, however, since I am a new maintainer I will just defer to people more experienced than me.
