   |  CPPFLAGS =	-I/usr/include
   |  .if ${.PARSEDIR:_}
   |  CPPFLAGS +=	-I$_
   |  .endif
   |  CPPFLAGS +=	-I/usr/local/include
 
 That works, once, but if you do it again, $_ will be changedm
 and all of the -I$_ will expand to the same thing when CPPFLAGS
 is eventually expanded.
 
 It is also still cumbersome to use (3 lines where just 1 should be
 needed).

 No problem with that, these various ways that almost work, but
 don't really, are just more reasons to add something easy to
 use which does work.
 
 But I will tell you to send in the developer paperwork, so you could
 work out a suitable real solution and implement & commit it yourself!
