Such substitute makes the output of "set extended-prompt \w" different from the output of "pwd" nor "os.getcwdu()" (gdb) python print os.getcwdu()^M \\build2-lucid-cs\yqi\yqi\arm-none-eabi (gdb) pwd^M Working directory \\build2-lucid-cs\yqi\yqi\arm-none-eabi (gdb) set extended-prompt \w \\\\build2-lucid-cs\\yqi\\yqi\\arm-none-eabi My patch doesn't work due to this difference. I'd like to know whether the substitute is necessary or not. --=20 Yao (=E9=BD=90=E5=B0=A7)
