Recent patches to fix handling of Ctrl-C when interacting with ssh are not portable to mingw, which lacks termios handling. The simplest solution is to just compile that code out, and if someone ever appears that has a serious interest in getting virsh fully functional even with ssh connections, they can provide patches at that time. * tools/virsh.h (_vshControl): Make termattr conditional. * tools/virsh.c (vshTTYIsInterruptCharacter) (vshTTYDisableInterrupt, vshTTYRestore, cfmakeraw, vshTTYMakeRaw) (main): Likewise.
