------- Additional Comments From austern at apple dot com 2004-11-18 21:39 ------- We have a lot of options that are vaguely similiar to this. It's also reminiscent of -iprefix. But I actually think the closest analogy is to -B. Its effect on header and library paths is the same as -B, but it doesn't change the search for compiler executables.
And while Syd is right that Apple would find this feature useful, I don't think there's anything about it that's specific to Apple or Darwin. I expect it to be generally useful for people who are trying to deal with multiple similar-but-not-identical versions of an operating system. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18555
