[Bug c/26490] New: tree check fail on valid C code

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I just tried to compile Suse Linux package graphviz-2.6-9 with a recent
GNU C++ compiler version 4.2 snapshot 20060225. 

The compiler snapshot said

-I../../lib/common -I../../lib/gvc -I../../lib/pack -I../../lib/pathplan
