gdbserver 6.7.1 for mingw32ce connect to host gdb problem

using the newly supplied build script, the bfd patch is applied and the
build is clean.

but now I am struggling to get gdbserver to accept a connection from
development host using target remote xxxx

first I noticed that gdbserver needs a command line like this

gdbserver.exe 169.254.2.2:9999 \\path\\test.exe

without path to .exe it just exits with a usage message
this is due to the fact that wince doesn't define a default (current)
directory like '.'

Test over RNDIS and WLAN with the same results. gdbserver times out after
about 8 seconds

on the host
arm-wince-mingw32ce-gdb test.exe
target remote 169.254.2.1:9999

returns Connection refused

tcp test is OK, able to ping the IPAQ 2795 target.

I'm kind of stumped. I hacked a few diagnostics into gdbserver/server.c to
try and trace what was going on. I wondered about __MINGW32CE__ asserted in
the make CFLAGS

any ideas what might be going on, or how best to trace this?

thanks

Thanks to all the help from Pedro on this. I'm including a build script
that patches gdb 6.7.1 and builds gdb and gdbserver. not sure the best way
to post this so I'll just include it inline for now.

#!/bin/bash
# build-gdb-6.7.1-mingw32ce
# built with mingw32ce distro 0.51
#

src=gdb-6.7.1
patchfile=mingw32ce.patch

echo "UNTAR $src DISTRO"
tar xvzf $src.tar.gz

echo "PATCHING $src DISTRO for mingw32ce"
cd $src/bfd
# using bfd patch submitted by Pedro 2007-12-10
patch < ../../mingw32ce.patch
cd ../..

echo "BUILDING GDB"
mkdir build-gdb
cd build-gdb
../$src/configure --target=arm-wince-mingw32ce --prefix=/opt/mingw32ce
make
make install
cd ..
echo "GDB BUILD COMPLETE"

echo "BUILDING GDBSERVER"
mkdir build-gdbserver
cd build-gdbserver
../$src/gdb/gdbserver/configure --host=arm-wince-mingw32ce
make
arm-wince-mingw32ce-strip gdbserver.exe -o gdbserver-stripped.exe
echo "GDBSERVER BUILD COMPLETE"
echo "copy gdbserver-stripped.exe to the device and rename it gdbserver.exe"
cd ..

Build gdb with --target=arm-wince-mingw32ce Build gdbserver with
--host=arm-wince-mingw32ce

I had never submitted it upstream ...
