[aspectc-user] Error "1><anonymous unit>(1): error: invalid declaration near token `:'"

[Luigi 'Comio' Mantellini]

Dear all,

I'm trying to write a AspectC++ version of Proxy Pattern, but I have
the following error:

1><anonymous unit>(1): error: invalid declaration near token `:'

I don't know where I have made the mistake... can you help me to
understand the error?
(I'm using the trial version of AspectC++ plugin for VC).

Thanks in advance

luigi
