From c8afb6c4b5756848e332ee1cae77c73cfda98eea Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 7 Jan 2007 09:51:05 -0200 Subject: Fix compilation on ppc32 architecture From: Mauro Carvalho Chehab There's a problem, pointed by Meelis Roos , that, on ppc32 arch, with some gcc versions (noticed with prerelease 4.1.2 20061115), compilation fails, due the lack of __ucmpdi2 to do the required 64-bit comparision.
