Yes, you're using autoconf 2.53b, whereas I was using autoconf 2.53.
The difference is irrelevant here.

The problem is that you're not quoting the arguments of your macros
correctly.  This issue is discussed at length in the Autoconf
documentation.  Your macros should look something like this:

AC_CHECK_LIB(popt, poptGetNextOpt,
        [AC_CHECK_HEADER(popt.h,
                foo=1,
                [AC_MSG_ERROR(*** Cannot find popt.h header); exit])],
        [AC_MSG_ERROR(*** Cannot find popt library); exit])

but you're misssing the square brackets.
