OK.  Assuming that AC_PROG_CC_C99 deprecated and then removed, how I
supposed to express "give me c99 or higher compiler or raise error if
there only c89 or lower compiler found"?  In another words: How can I
set the _lower_ bound of C standard support, after that configure
should stop trying and just raises an error?
