For programs' resources instead the resources should be found in a path

here. In general, this part is easier to do since most platforms
including Mac OS X have a way to find the executable.
_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.
