[Bug bootstrap/13477] New: Bootstrap failure: gcc/gcc/combine.c:10294: warning: 'mask' might be used uninitialized in this function

[wanderer at rsu dot ru]

I can't bootstrap tree-ssa branch CVS gcc at FeeBSD 5.1:

using both system compiler gcc (GCC) 3.2.2 [FreeBSD] 20030205 (release)
and mainline CVS gcc;

using both binutils version 2.13.2 [FreeBSD] 2002-11-27
and mainline CVS binutils.

Last time when i can bootstrap tree-ssa breanch GCC is 2003.12.11
