[svn-r26495] Description:

    Bring r26258 from the autotools_rework branch to the trunk - remove
the LDOUBLE_TO_INTEGER_WORKS macro/define, which was addressing issues with
SGI systems that are no longer supported.

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