[svn-r26623] Description:
Bring r26513 from autotools_rework branch to trunk: Remove the LDOUBLE_TO_LLONG_ACCURATE macro/define, it's working around bugs in older SGI, HP/UX, MacOSX and Windows .NET 2003 compilers. Tested on: Linux/32 2.6.18 (jam) w/serial & parallel (Daily tested on branch for 2+ days)
