OK, I have found a Portable Objective-C compiler (http://users.telenet.be/stes/compiler.html).
A MorphOS pre-built binary is available on Aminet.
But this does not contain the GNUStep runtime.

If Synergy server is done in Objective-C and this was compiled for MorphOS I'd really like to know more.
Hard to find anything though.
