    Remove some configure header-file checks that we weren't really using. · 2bd7f857
    Tom Lane authored
    We had some AC_CHECK_HEADER tests that were really wastes of cycles,
    because the code proceeded to #include those headers unconditionally
    anyway, in all or a large majority of cases.  The lack of complaints
    shows that those headers are available on every platform of interest,
    so we might as well let configure run a bit faster by not probing
    those headers at all.
    
    I suspect that some of the tests I left alone are equally useless, but
    since all the existing #includes of the remaining headers are properly
    guarded, I didn't touch them.
