Subject: bug#13118: [PATCH] factor: disable longlong.h logic for x32 builds
Date: Fri,  7 Dec 2012 15:44:18 -0500

The current x86_64 asm code does not work for x32 ABIs, so disable it
until someone can fix it.  Simply deleting the q suffix is not enough.

* src/longlong.h: Check for __ILP32__ for x86_64 targets.
