I think that's a bad idea; having too many ways to configure things will cause undue confusion. But if someone really wants that and really knows what they are doing, it may be possible for them to do something with --with-specs. (C deliberately has not been moved to gnu99 as default because we don't have a -Wc90-c99-compat or similar option to warn about things different between C90 and C99, so anyone using -pedantic to warn about things outside C90 wouldn't be able just to use -pedantic -Wc90-c99-compat with a gnu99 default, they'd have to set the standard back to gnu89 as well. Given such an option - which should generate warnings, not pedwarns, for the cases that are presently pedwarn-if-pedantic-if-C90 (and a few other cases), changing the default to gnu99 would make sense - in Stage 1.) -- Joseph S.
