Your macro still lacks proper quotation.  You need to [quote] at least
the third argument of the AC_CACHE_CHECK call, but better all others
too, as well as each argument of AC_EGREP_HEADER.

If that still causes the error above, then it would be helpful to see,
say, a dozen lines of the configure script around the line where the
error occurs.
