Mangling question

[Joe Kelsey]

I was trying to figure out why my class wasn't defined due to linker 
errors I received.  The linker complained about undefined symbol

_$_6Shared

Where Shared is the name of the undefined class.  I read the mangling 
documentation and I cannot figure out where this comes from.  $ is some 
sort of static indicator, so what is _$_?  Indicating the static 
constructor?

Also, what are

__ti6Shared
__tf6Shared

t means template, i means integer and f means float, but the constructor 
is not a template nor does it take a float argument or return a float 
argument.  And the extra underscores are not for BSD compatibility, as 
the normal method name mangling does not start with an underscore.

Maybe the mangling document needs updating.

p.s., the undefined problem was due to a stupid programming error, pure 
virtual destructor when what I needed was an empty virtual destructor...
