   No workaround should be required; it is supposed to all "just work".

   Can you post a snippet of code and the command line you use to
   compile?

The following code, call it test.c,

#include <unistd.h>

main()
{
        int p;

        p = vfork();
}

compiled using gcc -D__ELF__ test.c results in

Undefined symbol `__vfork14' referenced from text segment

Compiling without the __ELF__ links okay.
