Me too, (not available either). But there are several things which
make this a very difficult job in addition to the parsing problems
mentioned by others.


The actual layout of a structure is largely up to the specific compiler,
for such things as alignment, which in turn is controlled by


#pragma pack n


All of this makes the output you would get VERRRY non portable anyway
even from one compile run to the next. I would suggens taking another
look at exactly what you need this information for and see if there is
not another way than spelunking the source.
