 I agree with you that my problem application rely upon nonportable behaviour.
 This is not reason for not including this patch.
 
 My points for including this patch are:
 
 1) do not breaks ISO standard
 2) do not breaks existing apps
 3) improve FreeBSD source code compatibility with other OSes, because these OSes are doing the same.
 4) fixes problem with my application, which is large (10MB) and difficult to fix.
 
 In summary: This patch will make things better, not worse. I do not know
 about negative side-effects.
