From c622cc7b38791567a6e41d147121a76a20837e96 Mon Sep 17 00:00:00 2001 From: Quincey Koziol Date: Wed, 25 Mar 2015 17:11:19 -0500 Subject: [svn-r26595] Description: Bring r26494 from autotools_rework branch back to trunk: Remove the LDOUBLE_TO_UINT_ACCURATE macro/define, it was addressing problems with older Intel compilers on Linux that are no longer supported.
