Separating "shell dir" output from GDB/MI output

[jingzhao.ou]

Dear all,

I am trying to see if it is possible to build a Tcl/Tk based GDB
frontend using Bob Rossi's MI parser. For normal commands, it works
just fine. However, if I execute "shell dir" command in gdb, the
parser will report error. (see the end of the email)

I am wondering if there is any way to separate the shell output from
the normal GDB output. So that this problem can be solved properly.

Sincerely hope that any one can give me a hand. I am using MinGW.

Best regards,
Jingzhao
