>! is not available in pure Bourne shell and should be avoided. Minor nit: ! is in POSIX; the problem here is Solaris has an ancient sh implementation (isn't there a POSIX one in something like /usr/xpg4/bin ?). Same with -E for grep. I'm fine with workarounds for Solaris, but I'm wondering if we want to tackle this in a different way. Example: we could use AC_PROG_EGREP for the grep issue (although Oliver's suggestion to combine it into awk seems reasonable as well). I'm neutral on solutions for the problem with POSIX shell constructs; we could either get rid of them or have autoconf pick a better shell. --Ken
