zmq22: error: non-constant-expression cannot be narrowed from type 'long' to '__darwin_suseconds_t' (aka 'int') in initializer list

Description

​zmq22 does not build with newer compilers: 

select.cpp:162:13: error: non-constant-expression cannot be narrowed from type 'long' to '__darwin_suseconds_t' (aka 'int') in initializer list [-Wc++11-narrowing]
            (long) (timeout % 1000 * 1000)};
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
select.cpp:162:13: note: insert an explicit cast to silence this issue
            (long) (timeout % 1000 * 1000)};
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            static_cast<__darwin_suseconds_t>( )
1 error generated.

Newer compilers default to C++11 mode. If this code can be made compatible with C++11 mode without requiring it, great. If not, you can specify an earlier mode with: 

configure.cxxflags-append -std=c++98

This also affects zmq3, however I did not manage to personally reproduce this issue for either port. This issue was addressed upstream: ​https://github.com/zeromq/libzmq/pull/1181

I have opened a pull request adapting the upstream fix: ​https://github.com/macports/macports-ports/pull/8395
