A second GCC 4.6.0 release candidate is available at: ftp://gcc.gnu.org/pub/gcc/snapshots/4.6.0-RC-20110321/
Please test the tarballs and report any problems to Bugzilla. CC me on the bugs if you believe they are regressions from previous releases severe enough to block the 4.6.0 release. If no more blockers appear I'd like to release GCC 4.6.0 early next week. Jakub
