[svn-r26624] Description:

    Bring r26584 from trunk to 1.8 branch:

    Bring r26485 from the autotools_rework branch to the trunk:

    Remove the ULONG_TO_FLOAT_ACCURATE macro/define, we no longer support the
Sandia system where it was necessary.

Tested on:
    Linux/32 2.6.18 (jam) w/serial & parallel
    (Daily tested on trunk for 2+ days)
