Introduce a means to distinguish failures of `configure' due to
extern software (so that the test suite doesn't fail on them). * acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an optional $2: exit status. * doc/autoconf.texi: Document. * acspecific.m4 (AC_PROG_CC_WORKS, PROG_CXX_WORKS, AC_PROG_F77_WORKS): Exit 77 if the compiler does not work.

Clean up a bit the handling of the LANG stack. More is needed.
