I haven't been using OpenBSD for years, so I'm not sure why there is an 
/usr/include/objc header directory that does not match the compiler. But 
anyway, this is a problem that you'll see on every system where you use a gcc 
version which does not match the default compiler. Gcc knowns about the special 
directory containing the Objective-C headers and includes that in the default 
search path. However, that applies only to Objective-C files and not to plain C 
files like runtime.c. I think the best way to move forward would be renaming 
runtime.c into runtime.m so that this file gets compiled with the correct 
search path.
