title: compiled gdb doesn't show debug symbol in Tui mode?
body: <p>I compiled gdb source code from scratch on wsl2 in windows 11. And i got lots of errors about the macros and some function interface.I just solved them by hand. Finally i  got a gdb elf file,and it work well without Tui mode, but it doesn't show symbol info in Tui mode.</p>
  <p>some pics record them. The color of tui mode also seems a little unstrange comparing to original one in wsl2.</p>
  <p>The first three figures are compiled GDB(tui mode)</p>
