OK with the argument to AC_MSG_ERROR []-quoted (i.e.,

AC_MSG_ERROR([unknown libssp setting $enableval])

which should not change the generated configure script) - the preferred 
autoconf style is generally for each macro argument to have one level of 
[] quotes unless there is some reason for a different level of quoting, 
although gcc/configure.ac is not wonderfully consistent about this.
