The documentation states:

     In addition, `-I-' inhibits the use of the directory of the current
     file directory as the first search directory for `#include "FILE"'.

I believe that this is the behavior you are relying on.  The -iquote
option does not do this, nor can I find an alternative switch that does
so.

A quick google search of "site:gcc.gnu.org iquote" finds a good chunk of
relevant information.  Please check it out.

Anyway, gcc is behaving as documented, AFAICT.  You may wish to
re-purpose this bug as a wishlist "Please undeprecate -I-" or somesuch.

Thanks,
