Description (last modified by bennylp)

Bug in pj_strcmp2() will cause pj_strcmp2("1", "12") to return equal.

Checking other string functions reveals that some string comparison functions are not exactly compliant with ANSI. For example, given:

  char *s1 = "2";
  char *s2 = "11";

With ANSI, strcmp(s1, s2) will return 1, while with pj_strcmp(s1, s2) will return -1.

The reason why the result was different was because string comparison in PJLIB was too optimized for speed, so it only cares about the fact that the string was different.
