Re: Using Win32Com with Ada

[Hang Xie <xiehang@gmail.com>]

It seems -fdump-ada-spec does not work quite well with header files come 
with Windows SDK - does anyone have any good experience to share? 
Specifically, I was trying to roll out DirectShow specification but 
encountered way too many errors.

I haven't tried yet but I assume it works fine on *nix or header files 
targeting gcc, anyway Windows is just 2nd (maybe 3rd) tier platform for 
most open source projects.
