c++: -Wdeprecated-copy and using operator= [PR92145]
For the purpose of [depr.impldec] "if the class has a user-declared copy
assignment operator", an operator= brought in from a base class with 'using'
may be a copy-assignment operator, but it isn't a copy-assignment operator
for the derived class.
gcc/cp/ChangeLog:
PR c++/92145
* class.c (classtype_has_depr_implicit_copy): Check DECL_CONTEXT
of operator=.
gcc/testsuite/ChangeLog:
PR c++/92145
* g++.dg/cpp0x/depr-copy3.C: New test.
