[aspectc-user] __declspec issues

Hmm, I got to get this working in opensource so purchased products aren't
in the picture :-(

However, I got this working (at some level) by using the --vc option
(thanks to Matthias Urban <matthias.urban at pure-systems.com> ) and then I
had to use the --problem flag (don't really know what it does but it got
rid of some more errors that I was having with "string"

I've still got issues with other stuff and I think I mailed Matthias
directly by mistake so hopefully he'll copy everyone on the reply if it
helps anyone else !

Hi John,

Most of the MS-specific language extensions are only parsed correctly
with the commercion version of ac++.exe, which is developed and sold by
pure-systems GmbH (http://www.pure-systems.com/) as part of their
VisualStudio AddIn.

As a workaround you may use "#ifdef __puma" which is defined during
parsing and weaving:

#ifdef __puma
    #define STORAGE_CLASS_INFO __declspec(dllexport)

or, as a more general solution

#ifdef __puma
    #define __declspec(some_argument)

Have fun!
