Hey guys,

as the title says, I didn't get ./configure to detect the installed
libg15render (it found the header and all, but the linking failed with
the g15r_initCanvas function).
The problem seems to be that libg15render needs also to be linked with
the math library for the ceilf() function.

The attached patch fixed this for me, but please someone tell me if this
is "the right way" to do it :-)

Thanks a lot,

Robert
