[gme-users] BON2 interpreter - VC7.1 warning C4930 seems harmful

Hi,

I've fixed the InterfaceColl.h file (Interfaces folder) to get rid of 
those errors. The changes will be included in the next release. 
(ComponentLib.h is a generated file, so it's not the best place to fix 
the errors).

Unfortunately, I'm not the one who wrote that line. However, it seems we 
need to get that construtor called. So, please modify the line:
FCO fco( getType() );
I have updated our version in the CVS.

Modify the line (BONImpl.cpp, 69):

return (IMgaMetaBase*)spMeta;

I have updated our version as well.

It seems those warnings (the causes) are generated by the dsw->sln 
conversion. They are not serious, just fix them or leave them.

Thanks for your valuable report.
