From ea2a03e983acf34a1320b460dcad43b7e0b0b14f Mon Sep 17 00:00:00 2001
Message-Id: <ea2a03e983acf34a1320b460dcad43b7e0b0b14f.1397134306.git.baruch@tkos.co.il>

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.
Patch status: reported upstream,
https://bitbucket.org/libgd/gd-libgd/issue/123/build-failure-agains-uclibc-arm
