>Description:
Problem during the parsing of gcc-**/gcc/builtin-attr.def
the argument 1_0 is understood as 1,0 or something like
that (definition of DEF_FORMAT_ATTRIBUTE).
when the problem is fixed (see below), it builds all stage1
and then fails (but that's an other story).

>How-To-Repeat:
"make bootstrap" on darwin with cc compiler:
cc -v
"Reading specs from /usr/libexec/gcc/darwin/ppc/2.95.2/specs
Apple Computer, Inc. version gcc-932.1, based on gcc version 2.95.2 19991024 (release)"
>Fix:
bracket args 1_0 or any *_* into "*_*".
(sorry, I know this is not the way to do it,
 but I can't help putting a diff file...)
