From 6b8a872ff1038e2b8618ea33bb1113b78f39976d Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Thu, 22 Jan 2015 20:23:12 +0200 Subject: [PATCH] Fix MinGW TUI build gdb/ 2015-01-22 Eli Zaretskii * gdb/tui/tui.c (tui_enable) [__MINGW32__]: If the call to 'newterm' fails with the 1st arg NULL, try again with "unknown".
