In part, yes.

The 'no-strict-aliasing' parameter was added for a reason (which I can
no longer recall :-() so I was curious if I should be looking for
related regressions now that it has been removed.

That is:

1) if the breakage that prompted its addition has since been resolved to
now permit its absence?

 .. or ..

2) if the c99/gnu99 mode incorporates a re-interpretation (by gcc) of
aliasing methods so this parameter is no longer required?
