Hi Eric,
On OpenBSD 4.4, which uses a gcc version 3.3.5, I get these warnings:
test-ignore-value.c:35: warning: `__warn_unused_result__' attribute directive
ignored
test-ignore-value.c:36: warning: `__warn_unused_result__' attribute directive
ignored
test-ignore-value.c:37: warning: `__warn_unused_result__' attribute directive
ignored
test-ignore-value.c:38: warning: `__warn_unused_result__' attribute directive
ignored
test-ignore-value.c:39: warning: `__warn_unused_result__' attribute directive
ignored
The reason is that __warn_unused_result__ was introduced in gcc 3.4, not
in gcc 3.1, as the code appears to assume. OK to fix this?
