Summary

0000400: Compiler warning in ap.h

Description

Using gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5), I get the following warning:

ap.h:719: warning: type qualifiers ignored on function return type
ap.h:720: warning: type qualifiers ignored on function return type

These are the two lines:
const bool operator==(const alglib::complex& lhs, const alglib::complex& rhs);
const bool operator!=(const alglib::complex& lhs, const alglib::complex& rhs);

I guess the const flag can be savely removed for bool return values.

Steps To Reproduce

Notes
(0000070) zaytsev (reporter) 2018-01-03 08:47	It doesn't have anything to do with booleans per se, but rather with non-class (POD) rvalues: https://stackoverflow.com/questions/1607188/why-is-a-type-qualifier-on-a-return-type-meaningless But yes, the bottom line is that the const qualifier can be safely removed in this situation.
