- 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
- Signed-off-by: Baruch Siach <baruch@tkos.co.il>
