ac_dir is an internal data which may disapear.

Checkout AC_PATH_PROG in such a case. Either you want the full path,
or you don't, but mixing is probably not right. User with a broken
path should handle their own problems themselves.

No, PATH is here for this.
I've had similar requests from users and finally used the macros
below. The style is *very* bad, in fact, I'm quite ashamed, but I
wrote this long ago :)
