Hi Bill,


as documented on http://gcc.gnu.org/install/configure.html it's a bad
idea to use a build directory inside the source tree:
"First, we highly recommend that GCC be built into a separate directory
from the sources which does not reside within the source tree. This is
how we generally build GCC; building where srcdir == objdir should still
work, but doesn't get extensive testing; building where objdir is a
subdirectory of srcdir is unsupported. "

So probably that made the difference...
