#include fails to look on same directory as source

[apalala]

With base.ebnf and full.ebnf in the same directory with:

#include :: base.ebnf

Will search for the include in the current or parent directory, and fail.

+1. And I found another issue. When #include are chained, the first #include must be written from the parent directory, but the next #include must be written with a relative path.
