Hello,

This patch allows the use of typedef'ed names as arguments in structures, if the
structure is defined in an external C block. By this handling gets
more similar to
C. If the the option -fms-extensions is enabled, this is also allowed
for class in C++ - like the option -fpermissive.

This adjustments helps mingw and wine to mimic the behavior of VC in
such cases better.

ChangeLog for gcc/cp

	* class.c (note_name_declared_in_class): Make in 'extern "C"' blocks,
	or if -fms-extensions is enabled check, check permissive.


Patch tested for x86_64-w64-mingw32 and i686-w64-mingw32. Ok for apply?

Kai
