    This patch replace all strncmp(a, b, c) by  memcmp(a, b, c).

I test on x86_64 (AMD Opteron 285).

#include <string.h>
char *A = "0000";
void test_memcmp(void) {
        memcmp(A, "TEST", 4);
}
void test_strn(void) {
        strncmp(A, "TEST", 4);
}
# gcc -c -O2 test.c
# objdump -d test.o
...

0000000000000020 <test_strncmp>:
  20:   f3 c3                   repz retq
  22:   66 66 66 66 66 2e 0f    data32 data32 data32 data32 nopw
%cs:0x0(%rax,%rax,1)
  29:   1f 84 00 00 00 00 00

0000000000000030 <test_memcmp>:
  30:   f3 c3                   repz retq

Wow, minus  one commad :)
