If bzip2.exe is not on PATH, I don't expect this to work.

??? Isn't that what you would do on any other OS?  Also, bzip2 is
useful on its own right, unrelated to Emacs.

I think your problem is with exec-path (which is derived from PATH),
not with PATH directly.

IME, it's a bad idea to have exec-path inside Emacs be different from
PATH outside Emacs, because then you'd have subtle differences between
Emacs looking for programs and programs it invokes (such as the shell,
for example) looking for programs.  So my advice is not to patch Emacs
that way.
