Also, it seems kind of | arbitrary to relax requirements here, while we make other macros | stricter in requiring standards conformance (gnulib is even much more | extreme in this case). Which means we can't change AC_PROG_GREP, but we can add AC_PROG_GREP_SIMPLE which guarantees only a grep that meets the simpler set of requirements. Then we can reformulate AC_EGREP_CPP (and thus AC_CHECK_HEADER) in terms of AC_PROG_GREP_SIMPLE (since that is documented to only search a single pattern), but users who still need multiple -e for other reasons can use AC_PROG_GREP. - -- Don't work too hard, make some time for fun as well!
