On i386 building strace from CVS emits following warning:

if gcc -DHAVE_CONFIG_H -I. -I. -I. -Ilinux/i386 -I./linux/i386 -Ilinux -I./linux   -Wall -g -O2 -MT syscall.o -MD -MP -MF ".deps/syscall.Tpo" -c -o syscall.o syscall.c; \
	then mv -f ".deps/syscall.Tpo" ".deps/syscall.Po"; else rm -f ".deps/syscall.Tpo"; exit 1; fi
syscall.c: In function ‘get_scno’:
syscall.c:788: warning: unused variable ‘pid’

Attached patch fixes it by disabling [1] for archs, which don't
actually use it. I successfully tested/compiled it on i386 and 


[1]  syscall.c: 788   int pid = tcp->pid;
