Is that the Windows port of Emacs or the DJGPP port?  If the former, then 
it won't work because the way Emacs redirects standard handles of the 
subordinate program (GDB, in this case) to a pipe is incompatible with 
how GDB handles input.  So GDB still thinks it is invoked from a command 
line and tries to read the keyboard directly.

If your Emacs is the DJGPP port, then it also won't work because 
asynchronous subprocesses aren't supported :-(
