I think you should avoid compile-time determinations like these as much 
as possible. Use run-time checks to see if you should do A or B 
instead. With compile-time decisions you never really know what the 
compiled code will do if you for example enable or disable something in 
a configuration file. Was the code compiled to include functionality X, 
which could therefor be enabled, or not?

Untested, but here is a way to do it at compile time :

  -define(DOBAR, true).

  myfun() ->
      foo(),
      ?DOBAR andalso bar(),
      baz().

or, with a function (want_to_do_bar()) that determines if bar() should 
be called or not :

  calling_function() ->
      DoBar = want_to_do_bar(),
      myfun(DoBar).	   

  myfun(DoBar) ->
      foo(),
      DoBaz andalso bar(),
      baz().

You get the idea.
