OK, committed[1].  You are right that it is not possible to warn if 
AC_DEFINE_UNQUOTED passes a shell variable with bogus content; here, the 
documentation should be adequate (just like we don't warn if the value contains 
`#' but the user didn't use AC_CONFIG_HEADER, where make will eat the # out of 
@DEFS@).
