This is not an issue since this is actually invalid C++ and has already been documented on http://gcc.gnu.org/gcc-4.1/changes.html: # ARM-style name-injection of friend declarations is no longer the default. For example: struct S { friend void f(); }; void g() { f(); } will not be accepted; instead a declaration of f will need to be present outside of the scope of S. The new -ffriend-injection option will enable the old behavior. Thanks, Andrew Pinski
