Problem is Fedora rel 11 compiler is botched. Made a copy of /usr/include/stdio.h in $ROOT/platforms/unix/vm/stdio.h Edited this file removing dprintf (starting line 399) Changed: #include <stdio.h> to: #include "stdio.h" whenever had problem.
in file debug.c included line #include <stdlib.h>
Dirty work. But fix things... :(
