Re: Unchecked_Union record inside an other record - trouble

Yes of couse -fdump-ada-spec is for GCC-gnat but even if you want to 
take a small subset I find it more efficent and much less errorprone to 
start with the generated spec:s and edit the generated code  afterwards.

(have done this with a fairtly large API:

550 header-files
7500 methods
5500 types

and some small ones as well.
