I recently regressed on this on branch-1.6, by introducing a test that 
recursively calls m4.  In the installed case, it should instead recursively 
call __program__ (in the uninstalled case, it hasn't yet been renamed, so 
calling m4 didn't trigger any problems).  I'm still working on making the 
master branch support this, but it is taking more work (in part because it is 
harder to trace through libtool wrappers to test with a cooked executable 
name).  And I may still yet borrow an idea from coreutils' maint.mk, to enhance 
the maintainer-specific rule 'make my-distcheck' intentionally add a crippled 
m4 at the front of the PATH, to ensure that all the tests properly use gm4 when 
the name has been transformed.
