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...
