I originally provided the :tl and :tu patch for something like that
(not planning any abuse mind ;-)

But, if portmgr test my "patch" and find it works "ok" (for some value of
"ok") for older releases, this probably isn't necessary?

It may still be useful though to provide an updated fmake via ports,
which could make it easier for folk to migrate other code bases.
The sed script to be applied to makefiles is trivial btw:

$ cat f2bmake.sed
/$.*:[UL][:)}]/ { s,:L,:tl,g;s,:U,:tu,g; }
$
