    It is only cosmetic, for on the alpha, after configure is run,
ALIGNOF_{LONG,DOUBLE,ALIGNOF} all equal '8'. Further testing showed that
the macros LONGALIGN, DOBULEALIGN, and MAXALIGN generate the same result
when provided with the same input value. Therefore, I don't see anyway
that changing DOUBLEALIGNs to MAXALIGNs would reduce unaligned traps on
the alpha. :(
    PS. I am testing an alpha patched 6.5.1 right now, and so far it
looks promising. :) Final results soon!
