Jonathan Wakely 97271bd88f P0935R0 Eradicating unnecessarily explicit default constructors ... This is the last remaining piece of P0935R0. This adds a default constructor to each of the streambuf and stream types in <sstream> so that default construction does not use the 'explicit' constructor that has a single, defaulted argument. P0935R0 Eradicating unnecessarily explicit default constructors * config/abi/pre/gnu.ver: Tighten existing patterns and export new default constructor symbols. * include/std/sstream (basic_stringbuf, basic_istringstream) (basic_ostringstream, basic_stringstream): Remove default arguments from explicit constructors taking ios_base::openmode and add separate non-explicit default constructors. * testsuite/27_io/basic_istringstream/cons/default.cc: New. * testsuite/27_io/basic_ostringstream/cons/default.cc: New. * testsuite/27_io/basic_stringstream/cons/default.cc: New. * testsuite/27_io/basic_stringbuf/cons/char/default.cc: New. * testsuite/27_io/basic_stringbuf/cons/wchar_t/default.cc: New.
