From 0826779b99b49f7f8df5d186f3c481b6007010d4 Mon Sep 17 00:00:00 2001 From: Philippe Waroquiers Date: Tue, 9 Jul 2019 19:36:17 +0200 Subject: [PATCH] Fix printcmds.exp failure for wide strings tests. wchar_t type must be known to create wide strings. As this type is predefined when current GDB language is C++, switch to c++ for the wide strings tests.
