ISO C issues with enum int

[Juan Pablo L]

Guys, i m building a library for a project that is not under my
control, i can not control de Makefiles either as they are
autogenerated. i m using libev and i m getting the following error:

/libev/ev.h:206:17: error: ISO C restricts enumerator values to range
of ‘int’ [-Werror=edantic]
/libev/ev.h:228:17: error: ISO C restricts enumerator values to range
of ‘int’ [-Werror=edantic]
cc1: all warnings being treated as errors

i can not turned off the pedantic flag and for the above reason. any
suggestions ?
i m using gcc 4.6.1 and libev 4.11.

thanks!
