Bug #: 50244 Summary: wcstold not available for C++0x Classification: Unclassified Product: gcc Version: 4.5.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: lcid-f...@gmx.net When trying to include <string> and compiling with -std=gnu++0x I get loads of messages that wcstold is not defined. When looking at the system headers it seems that wcstol* are only added for GNU99 mode.
