Description Erez Strauss 2011-12-21 19:49:57 UTC 
Please update the definition of the EPOLLET constant to be

(1U<<31)

instead of

(1<<31)

as compilers (intel) are generating the warning:
.... : warning #68: integer conversion resulted in a change of sign
        unsigned m = EPOLLET;
                     ^


The epoll events is defined as unsigned 32 bits.

Thank you.
