src/tools/compat/compat_defs.h contains this macro definition of 
__USE:

138:#undef __USE
139:#define __USE(a) ((void)(a))

It appears that pcc has not been properly set up to use the 
tools/compat infrastructure, so it's not getting the definitions 
from that file.  You could try adding these three lines near the 
top of src/external/bsd/pcc/dist/pcc/os/netbsd/ccconfig.h:

#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif

but I don't know whether that will be enough.
