indeed this is tricky.

First I tried renaming runtime.c to runtime.m and compile it with ObjC.

It does not fix the issue.

then I tried including thr.h instead of objc-api.h and thr.h, but it is 
not enough, one symbnol I miss is in runtime.h
If I include that, I get tons of redefinitions, likle this:

In file included from runtime.m:36:0:
/usr/local/lib/gcc/i386-unknown-openbsd6.4/4.9.4/include/objc/runtime.h:284:20: 
error: conflicting types for 'object_getIndexedIvars'
 objc_EXPORT void * object_getIndexedIvars (id object);
                    ^


I wonder a bit what kind of magic we are doing there: I actually wonder 
how it works elsewhere where I use even more modern GCC.
