[Bug c/20535] New: add warning or error if storage size mismatch

[olh at suse dot de]

We see more and more code like this, in this case e2fsprogs blkid:

char c;
c=getopt(...)

getopt returns an int, and so does getc.
But gcc stores the thing in something that cant hold the return type.

It should warn with an obvious message, or even error out.
