       * gdb/ui-style.c (colorsupport) [__MINGW32__]: MS-Windows always
       supports at least 8 colors, even if the "Co" capability is not in
       the terminfo DB.  This fixes "set style FOO foreground COLOR"
       commands in the Windows native build of GDB.
    
    (cherry picked from commit 0dbdf282cdf6b54006601ab5f1ed7bf5fbb6e0ab)
