Yeah - the following should do it:

# .if !target(foo)
foo: bar
	do_something
# .endif

The first rule encountered are used, while the last variable
definition encountered is used.  Thus, just defining the target
without any .if's should work.

Now, have anybody got a good way of exporting variables from BSD make
for me?  .export seems to be missing...  (Yes, I know I can type them
in for a recursive make, but it doesn't quite fit my standards of
'user friendliness'.)

You're probably right.  I'll see if we might happen to have a port of
bmake for Solaris lying around - I seem to remember some of my
co-workers saying they did one for a project here.
