Wconversion is implemented in the front-end and there is no data-flow solving
on front-ends, so basically it is impossible to know the value of i.
In addition, up to GCC 4.3, Wconversion was not meant to warn about
sig

Test program (Create a New Attachment is not working for me today):
const int i = -1;
unsigned int slip_one_by()
{
return i;
}
unsigned int caught_me()
{
return -1;
}
$ gcc -c unsigned_return.c -W
