c++ - Selective Warning Disabling

Walter,

Please accept the request to implement:

#pragma warning(disable:2)

to disable selective warnings.
I am not sure whether disabling errors like this is a good idea. (When would
that be useful?)

You can disable warning 2 from the command line using the switch:
    -w2

Yes, I know that, but when used in a makefile, it ignores the warnings for
all the files. What is required is that the warnings are to be disabled for
a specific file.

BTW, Ms-Windows code often has the same pragma, there it is disable:C2. You
could leave out that 'C' to take it as DMC warning number. (Any idea about
the 'C' in the first place?)

Also, I noticed that the IDDE does not show the warning number, only the
command line compiler shows it. Any reason?

Ok, I understand. I'll add it to the list.

No, Microsoft's design decisions can only be guessed at! <g>

Probably nobody thought of it.
