Tell GPRBuild to trigger an error on unknown options in project file?

Tell GPRBuild to trigger an error on unknown options in project file?

[Yannick Duchêne (Hibou57)]

Hi people,

I don't like when something does not behave as expected without an error  
message, or the same, get silently ignored.

As an example, I just wanted to pass a `--target=…` option to GPRBuild in  
the Builder package of a project file, but it was silently ignored. I  
later noticed the documentation indeed list this as part of the options  
that may only be passed to GPRBuild's command line, and not in project  
files [1].

Now I know, but I still feel it would be better to get a plain error  
message (and compilation failure) when an option is passed via the Builder  
package which GPRBuild does not handle.

Good sentiment.

You are sending this message to the wrong place; report@gnat.com would
be much more likely to get a useful response.

But I'm not a client, just an FSF GNAT user.

They do take note - I start the Subject: with (in this case) GPRBUILD:,
because they used to have a spam filter that required something like
that - but you don't always get a response.

It is possible to patch gprbuild, of course, but you have to work from
the GNAT GPL sources.
