When was AC_PROG_CC_C89 introduced? I like being able to use as old a version of autoconf as possible, and it looks like I'm going to need to go from using AC_PROG_CC to AC_PROG_CC_C89 now that I am no longer supporting K&R C for one project... Speaking of which, how difficult would it be to list the "oldest" version that will support each autoconf macro?
