So, personally, I'd just have something like:
#ifndef PTRACE_O_TRACEFORK
# define PTRACE_O_TRACEFORK 0x00000002 /* from kernel-2.6.x */
#endif
...and assuming you handle the error return from PTRACE_SETOPTIONS, it
should mostly just work on all relevant systems.
The file gdb/linux_nat.c shows that GDB uses this trick, and many
other useful ones. Time to cut-and-paste.
