   OK, as I mentioned in another post in this thread I am still 
searching for a way to clean this up without changing command line 
parameters generated in the default case (I have an idea that might do 
it now but... off for a swim in the sea first :-)).

   Until then, here is how I got your hp_cxx toolset problem solved:

   I also found no way to lose the quotes directly in the action code so 
I transformed the TEMPLATE_DEPTH variable in the corresponding rule 
where quotes are handled as I expected them to be handled in the first 
place. Then I just used the modified TEMPLATE_DEPTH parameter directly 
in the action to add the corresponding command-line option.

   I'll commit something like this once I get the gcc command line 
options problem sorted out, but this should help you achieve what you 
need locally on your end.

   Btw, you mentioned needing this support for the acc toolset as well. 
What is the correct command-line parameter there?
