#11 Compile issues on OS X 10.5
I'm working on an older Mac OS X 10.5 (Leopard) with a PowerPC. Its ancient by most standards, but its a test platform for the processor architecture. Because Apple abandoned it some time ago, we need to build some stuff ourselves (like Git, which has a distant dependecy on libedit through another dependency).
The "_main", referenced from... error can be resolved by detecting OS X, and using -dynamiclib instead of --shared. See https://developer.apple.com/library/mac/documentation/DeveloperTools/Conceptual/DynamicLibraries/000-Introduction/Introduction.html.
The compat.h:4:1: warning: "__RCSID" redefined can probably be resolved by a guard like #ifndef __RCSID or an #undef __RCSID.

Sorry about the crummy formatting. It appears SourceForge honored the code block using back ticks, but it discarded all the newlines...
