Source directory override with #include "..."

[Arnaud Lacombe]

Hi folks,

There do not seem to be any other way to override the source directory
in the search path for #include "...", than using -Ioverride -I-.
However, -I- has been marked deprecated. If the removal ever occurs,
there will be no way to do the override.

Isn't it an option which should be available to the user ?

Thanks,
 - Arnaud
