I have just committed a configure.in fix that eliminates the need for
this change.  It turns out that the shell syntax failure was just the
tip of the iceberg: the real problem is that AC_PROG_CC *must* be run
even if there is a user-supplied CC setting.

There is: AC_PROG_CC makes sure that the supplied CC setting works,
and incidentally discovers a few other things like whether it is gcc.
Our problem was we were bypassing that macro if --with-CC was given.
