3.0beta build error for sockets.cpp

Similar issue mentioned by MatthewButterfly:
/home/adminuser/fastcgi++/src/sockets.cpp: In member function ‘Fastcgipp::Socket Fastcgipp::SocketGroup::poll(bool)’:
/home/adminuser/fastcgi++/src/sockets.cpp:523:27: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
if(events == pollIn)
^
/home/adminuser/fastcgi++/src/sockets.cpp:538:27: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
if(events == pollIn)

This is on Centos 6.8 with devtoolset-4 and cmake3 installed.

I changed both instances to use if(events & pollIn) and compile worked.
I haven't tested the binary produced but I assume it'll work as you only want to check if the EPOLLIN bits are set in the events.
