Hi, mpc-0.7 now has been released, you can get the package here: http://www.multiprecision.org/index.php?prog=mpc&page=download
Here's the official announcement: http://lists.gforge.inria.fr/pipermail/mpc-discuss/2009-September/000554.html Of particular interest in this release are bugfixes, especially for complex division, and the introduction of mpc_pow used for folding cpow{,f,l} inside GCC. Note the complex "arc" functions are still missing and are now projected to be available in a future release, probably 0.8. Please download, compile and run "make check" for this release and post your results as well your target triplet and the versions of your compiler, gmp and mpfr. All platform results are welcome, but I am especially interested in GCC's primary and secondary platform list. Thanks, --Kaveh
