  21 dnl FIXME: We temporarily define our own version of AC_PROG_CC.  This is
  22 dnl copied from autoconf 2.12, but does not call AC_PROG_CC_WORKS.  We
  23 dnl are probably using a cross compiler, which will not be able to fully
  24 dnl link an executable.  This should really be fixed in autoconf
  25 dnl itself.
