Maybe.  You could always do as strchr():

	char *strchr(const char *s, int c);

Then you don't need to cast the result.  The problem[*] is that you can't tell
the compiler that the return value should carry the same constness as one of
the arguments because you don't have something like C++ templates.

  [*] If indeed not having C++ or templates should be seen as a problem...
