#2048 Error 25.925 and similar sometimes wrong

[Josep Maria Blasco]

::Attribute A Get Get

produces

Error 25.925: Unknown keyword on ::ATTRIBUTE directive; found "GET".

But "GET" is not "unknown", but duplicate.

The same happens with 25.902 (e.g. with ::Method M Attribute Attribute), 25.901 (::Class C Public Public), 25.904 (:Requires R Library Library) and 25.903 (::Routine R Public Private).

When a subkeyword appears, all the related subkeyword disappear from the set of recognizable subkeywords. But this is too restrictive, as it makes it impossible to detect subkeywords that are wrongly duplicated, but perfectly known.

These can be fixed by modifying interpreter/parser/DirectiveParser.cpp. At first look, it seems that new error messages will have to be created for "duplicate" errors.

Unless I am mistaken, the introduction of new error codes presents little risk to existing programs, since these are errors occurring during syntax analysis.
