3.2.2 is pretty old.  The current version is 4.1.1.

I get these warnings with current gcc:

foo5.c: In function ‘main’:
foo5.c:6: warning: statement with no effect
foo5.c:7: warning: statement with no effect
foo5.c:8: warning: statement with no effect
foo5.c:10: warning: will never be executed

which looks OK to me.

gcc 3.2.2 is no longer supported, so the bug will not be fixed in that
old release.
