Just don't end your lines with backslashes (which causes the shell to
delete the following newline) and AC_MSG_FAILURE will give you multiple
lines of output.  Normally you'll want the first line to be somewhat
shorter (since configure will insert a prefix in front of the message).

Hope that helps,
