It's actually zap1. This writes the byte '\001' at offset 15 in the file
xyz. You can write zap1.c faster than I can post it :-).

The magic offset is for a priority byte in the object file header. Normally
the priority is 0. Priority 1 is used for stub routines such as a version
of _exit() that does not reference stdio. This feature is unportable and not
really supported so I haven't documented it properly. It's best not to write
libraries that depend on linkage tricks.
