[help-gengetopt] option name collision with builtin 'include' special directive

[Papp Gyozo (VBuster)]

Hi there,

Since version 2.19, it is possible to include other files (i.e., other 
configuration files) in a configuration file, by using the include syntax:

     include "filename"

Actually, we've run into the issue that our product has an option with same 
name: "include".

My concerns are:
- gengetopt runs fine without prompting there could be a potential problem.
- gengetopt has no option to disable this feature or rename the builtin 
directive.
  Ot at least I can't see, in this case please point it out to me.

Unfortunately, we are in crazy hurry to publish the version of our product and 
we must keep backward compatibility, too. So changing the application is not 
option this time again.
