Can you show here the prototype of DrawRectangle from Imagemagick?

Is that the only conflict?  If not, please show the others as well.

Does Emacs use DrawRectangle, from any or both these libraries?  I
guess at most one is used, or else you'd have problems in the Emacs
sources as well, not just in the headers.  If we don't need to use
both, you should be able to rename one of them with #define.

A better solution would be to lobby the maintainers of Imagemagick to
use names specific to the package.
