The changes are not to gcc, but to libstdc++.  #include <foo.h>, from what
I gather, is a non-standard relic of libstdc++ v2.  Apparently in v3, they
discourage this behavior.. (but it should just spit out a warning, not
fail to compile).  FWIW, you might want to check out:

http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/howto.html
^---This is where your <foo> vs. <foo.h> is discussed
http://gcc.gnu.org/onlinedocs/libstdc++/faq/

Not being a c++ person myself, I found a lot of useful information there
that I didn't know.  Hope that helps!

Cheers,
Nicholas
