[C++-sig] py++ and std::bitset

[Kirill Lapshin]

Roman,

Currently py++ (or, rather pygccxml) complains about std::bitset. It is 
a mere warning, and does not affect me -- I am not exposing any bitsets 
to python yet. Still I am a bit worrying that I might have such a need 
in future. It might very well be that this warning is really harmless in 
this particular case, and can be ignored. Could you verify my analysis?

I am using gccxml from CVS (reasonably recent, though not the latest) 
built on cygwin, cygwin gcc 3.4.4, Py++ and pygccxml 0.8.2.

The problem arises from _Base_bitset<size_t _Nw> that has member _WordT 
_M_w[_Nw]. Gccxml reports that max for this array is (_Nw-1) which 
pygccxml does not recognize (it expects a number).

_Base_bitset is a private base of std::bitset.

I am getting warning:
UserWarning: unable to find out array size from expression "(_Nw - 1)"

I suppose that won't affect exposing bitset since it is a member of 
private base, which I don't really have (and can't) expose anyways.

Is it so?

Can something be done on pygccxml to support templated arrays, and 
effectively remove this warning?

Regards,
Kirill
