Thanks for the reply,
The flags are being passed to the action using the on binding. The
action I thought was relevant I decided to echo the parameters passed
to it like:
actions LinkApplication bind NEEDLIBS bind EXTRAOBJECTS bind LFLAGS
echo "1: " $(<)
echo "2: " $(>)
echo "EO: " $(EXTRAOBJECTS)
echo "NL: " $(NEEDLIBS)
echo "LF: " $(LFLAGS)
echo "LL: " $(LINKLIBS)
$(CMD.LINK) -o $(<) $(>) $(EXTRAOBJECTS) $(NEEDLIBS) $(LFLAGS)
An this displays what i would expect. The LFLAGS are being passed into
the action using the on target format...
...found 1120 target(s)...
...updating 1 target(s)...

Is this particular warning specific to actions or can it occur as a
result of passing arguments to a rule? (Just trying to narrow down
location that could be causing the problem).
Is there a method of finding a list of all actions and what are being
passed to them? Maybe I can search through those to see if any other
actions are somehow being invoked with those LFLAGS as a second parameter.
