That is a problem on some platforms. If you don't know if the char* is 2-byte aligned, then casting it to guint16* can be a problem.

/usr/include/bits/socket.h: In function `__cmsg_nxthdr':

Unfortunately, there's not necessarily we can do about this one besides turning the warning level down. The warning in question is -Wcast-align, and one option is to turn it off for eel altogether.

eel-background.c: In function `eel_background_receive_dropped_color':
eel-background.c:1386: warning: cast increases required alignment of target

This one can probably be fixed by casting to void* first or something like that, but turning off -Wcast-align should deal with this too.
