[svn-r26491] Description:

    Bring r26257 from autotools_rework branch back to the trunk - removes
the LDOUBLE_TO_INTEGER_ACCURATE macro/define, which was addressing problems
with SGI systems and is no longer supported.

Tested on:
    Linux 2.6.x/32 (jam) w/serial & parallel
    Daily tested on branch for >2 weeks.
