The need for specifying the template depth has just come up for
boost.integer on cxx and acc, which both default to 64.

I tried adding

flags hp_cxx.compile.c++ OPTIONS <c++-template-depth> :
   -pending_instantiations <c++-template-depth> ;

to the toolset, but this results in only the feature value ending up in the
command line.


flags hp_cxx.compile.c++ OPTIONS :
   -pending_instantiations <c++-template-depth> ;

works, but results in always adding -pending_instantiations <n> to the
compiler command line, even when the feature is not specified.

Is there a way to not get the modification of the command line when the
feature is not specified?

I also tried

flags hp_cxx.compile.c++ OPTIONS <c++-template-depth>* :
   -pending_instantiations <c++-template-depth> ;

but this obviously doesn't work either.

And could we please change the first range of allowed feature values to
include 64 with a stepping of 64? Because 64 is the default value for both
acc and cxx.
