'define', 'include' keyword missing in C/C++ autoCompletion files

Description of the Issue

The keyword define (used as #define) and include (used as #include) in C/C++ files is missing from the 'autoCompletion/c.xml' and 'autoCompletion/cpp.xml' files. The keyword #define and #include is present; however, without # as an additionalWordChar in either file, typing #define never offers the autocomplete.

I've tried adding the additionalWordChar="#" but that doesn't seem to help. The simplest way may be to just add 'define' and 'include' themselves as keywords.

Steps to Reproduce the Issue

1. Open Notepad++ select C or C++ as language from menu
2. Ensure Settings => Preferences => Auto-Completion is enabled
3. Type #define
4. Notice #define is never offered as an autocomplete option.

Expected Behavior

#define is offered as an autocomplete option.

Actual Behavior

#define is never offered as an autocomplete option.
