reordering output messages from ENABLE_C99

[Phil Edwards]

Would anybody be offended by the following patch?  It shuffles some of the
AC_MSG_* statements in GLIBCPP_ENABLE_C99 so that they actually surround the
test statements, rather than doing the tests, then displaying "checking"
and the result all at once.  It lets me see where the pauses for checking
actually come into play; call it a pet peeve of mine.  :-)

It also moves a block of tests themselves so that we don't have nested
checking statements.  The semantics and results are unchanged.

Phil
