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...
