New 1:1 libpthread that was introduced in current along with new 1:1
threading was not binary compatible with the old SA libpthread from
4.0 b/c some structures changed their sizes.  As libstdc++ contains a
pthread mutex, it broke binary compatibility for C++ apps
(toolchain/38804).

Few days ago a fix was committed to current to pad new 1:1 libpthread
structures to match old SA libpthread to restore binary compatibility
for 4.0 apps.  Of course it broke binary compatibility with older 1:1
libpthread from current.  I guess a HEADS UP should have been posted
to current@ (hi, matt).

Yes, see above.

Yes.

At most the ones that has native code, I guess (I don't know it perl
XS ABI exposes this, or not).
