1) gdbserver currently ignores host part in HOST:PORT, so you can
just use '$GDBSERVER :$PORT $PATH'.

2) There is *no* notion of current directory on Windows CE. On
WinCE, every path *must* be absolute. (There is an
hardcoded $PATH, that looks of executables in \Windows and \ )

Gdbserver allows you to use forward slashes too:
gdbserver.exe :9999 /path/test.exe

And skip the .exe extension:
gdbserver.exe :9999 /path/test

I'm not sure what you're seeing. You should see something like
this:

\> gdbserver :9999 main
Process main created; pid=-1226757750
Listening on port 9999

Can you be more specific? (__MINGW32CE__ is automatically
defined by the mingw32ce compiler.)

Looks like something is not 100% right in your tcp/ip
connection.
Can you ping the host from the device ?
Is there any firewalling involved ?
Can you start gdbserver listening on 9999, and telnet it (to
remove gdb from the picture) with 'telnet $ip 9999' ?
