Since the commit cited below, the function has pretended to return a boolean. But every user expects it to return zero on success and a non-zero value on failure, like strcmp(). The function actually even returns "true" to mean "no match". This only makes sense if one considers a boolean to be a one-bit unsigned integer with no inherent meaning, which I do not think is reasonable. Switch the prototype back to int, and return 1 instead of true.
