I tried that over the weekend and it worked, but I wondered if it was 
the way to go. Thanks for the confirmation :) I've sent a patch for 
that[0] now.

With that resolved, CFLAGS can just be

CFLAGS += -O2 -g -std=gnu89 -pthread -Wall -Wextra
CFLAGS += -I../../../../usr/include/

I'll wait a bit more to see if anyone else has any comments, otherwise 
I'll send a v2 in a couple of days.

Thanks!
Emilio
