_NSGetExecutable returned garbage last time I used it, so I'd favour the 
same method as for libraries: libdl.

GNU libraries/utilities are likely to provide support for the earliest 
OSes, and libdl was absent till (I don't know which version exactly, 
10.3 or 10.4). Somebody has implemented libdl interface on top of Mach 
API, and it became part of Mac OS X.

I would better use libdl interface because Apple will care about it in 
the future OSes, but Mach API is sometimes being dropped (like it 
happened to _NSGetExecutable) or changed.

Proper handling of Mac OS X 10.2 - 10.6 would require using either 
system libdl or built-in one in the abscence of system one.
