Subject: [PATCH] The AIX doubledouble longdouble has been left broken for
 three years.

I must have left the test in the wrong position while
working on getting it to work, and never tested it since.
My apologies.

With this simple trick the following failing tests start to work.

        ../cpan/Math-Complex/t/Complex.t
        ../cpan/Math-Complex/t/Trig.t
        ../cpan/Math-Complex/t/underbar.t
        ../cpan/Scalar-List-Utils/t/uniq.t
        ../ext/POSIX/t/math.t
        ../lib/warnings.t
        op/sprintf2.t
        op/time.t

Or rather, the broken part of the functionality, Infinity,
starts being avoided, as it should be.  See the comment above
about the known brokenness of long doubles and infinity in AIX.

Note that even after this fix the following are still broken in
this AIX (the perl5 aix machine), but these are unrelated to infnan:

        ../cpan/ExtUtils-MakeMaker/t/03-xsstatic.t
        ../dist/Storable/t/store.t
        ../ext/XS-APItest/t/handy00.t
        re/uniprops01.t
        re/uniprops02.t
        re/uniprops03.t
        re/uniprops04.t
        re/uniprops05.t
        re/uniprops06.t
        re/uniprops07.t
        re/uniprops08.t
        re/uniprops09.t
        re/uniprops10.t
