--- Comment #4 from Dave Korn <davek at gcc dot gnu.org> 2010-11-09 21:00:47 UTC --- Created attachment 22354 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22354 proposed patch ISTM the main issue (common to this and Bug 46397) is C99, so this patch adds a test for its availability at top-level that disables lto-plugin if C99 can't be used (but doesn't make the compiler actually use C99 mode in general), and makes the lto-plugin itself use C99 mode to compile. It also adds stdbool support as shown in the autoconf man page. Rainer, could you give it a whirl?
