------- Comment #24 from fang at csl dot cornell dot edu 2008-01-16 22:21 ------- A compromise might be to provide the headers only if specifically requested, say, by -fbackward-headers (something more specific than -fpermissive). So by default, the compiler/preprocessor will now error out, but those desparate for a quick workaround can add a flag. I've seen too many projects/developers disregard the current backwards header warning (laziness? indifference?). Upgrading to an error with a workaround is yet another step on the road to deprecation. Yes, you'll still get some screams in the middle of the night (and bug reports), but at least this provides an easy way out.
(IANAM, but I'd be in favor of killing the pre-ISO headers over keeping them.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33831
