+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
