[svn-r26587] Description:

    Bring r26489 from autotools_rework branch to trunk:

    Remove the ULONG_TO_FP_BOTTOM_BIT_ACCURATE macro/define, as it was added
for SGI systems and old Solaris systems, which are no longer supported.

Tested on:
    Linux/32 2.6.18 (jam) w/serial & parallel
    (Daily tested for >1 week)
