From ea2a03e983acf34a1320b460dcad43b7e0b0b14f Mon Sep 17 00:00:00 2001 Message-Id: From: Baruch Siach Date: Thu, 10 Apr 2014 15:49:13 +0300 Subject: [PATCH] gd_bmp: fix build with uClibc Some architectures (like ARM) don't have the long double variants of math functions under uClibc. Add a local ceill definition in this case.
