New Revision: 260194
URL: http://svnweb.freebsd.org/changeset/base/260194
Log:
Revert r260073; small diff reduction wrt gcc43 and Apple GCC.
Unfortunately this causes ICE on powerpc and sparc64.
Reducing these differences against upstream is not important
anymore so hopefully I have finished breaking the compiler
occasionally.
