New description:

 Sage will not build with gcc 4.6.0 due to a number of issues. These need
 to be resolved asap, as Fedora 15 will ship with gcc 4.6.0.

 At least some of the problems that prevent Sage building with gcc 4.6.0
 are:

  * #10892 (lcalc)
  * #11083 (!PolyBoRi)
  * #11084 (Singular)
  * #11168 and #11437 (Rubiks)
  * #11226 (sympow)
  * #11227 (Cliquer)

 There may be others on specific platforms.

 When all these issues are resolved, the "Install from Source Code" section
 of the Sage Installation Guide needs to be updated to remove the notes
 about Sage not building with gcc 4.6.0. Also the Wiki at
 http://wiki.sagemath.org/SupportedPlatforms needs to be updated, as that
 now mentions that Sage will not build with gcc 4.6.0.

 The lcalc, Singular and !PolyBoRi issues have all been reported upstream.

Comment:

 I have updated the Wiki at  http://wiki.sagemath.org/SupportedPlatforms.
 I believe the patch reverts the changes of #11159 that mention gcc-4.6.0.
