Is it beginners 'blindness' or does LiteC ignore any #include if the include filename contains an underscore '_'?

From the manual:
Topic: #include

Looks like the underscore is an "nonstandard character".

Thanks for that, Rule 1 read the manual!

I would though have expected a compiler error/warning.
What happens is you get errors about undefined variables/functions it seems the include file is just ignored.

For me, it works with underscores. Maybe you use the wrong syntax or sth like that?

With the underscores it works...

I was using underscores with a file name exceeding 15 chars!

Ok I didn't read the manual and assumed a legal Windows filename was legal, but a thumbs down from the compiler would have been helpful.

You can use more then 15 characters in the name,
BUT the first 15 must be unique, otherwise the first
matching file will be used.

Many engine functions have just a 15 chars buffer, so it is recommented not to use file names longer than 15 chars.
