By using the patches of the Wcoercion project [*] and compiling with
-Wcoercion, gcc reports for the testcase mentioned in the description:

pr2707.c: In function 'main':
pr2707.c:8: warning: coercion to 'short unsigned int' from 'long unsigned int'
may alter its value

So I guess this bug can be closed as soon as Wcoercion is integrated into
mainline.
