Hi Michael,

I built x2goclient 4.0.3.0 with MSVC2010's nmake. 
Unfortunately couldn't do so with Visual Studio 2010 IDE.

I attach a release build of libssh 0.6.3 (please rename .doc to .zip). 
The sources are from libssh-0.6.3-762055b-pageant-support-mingw482.src.zip 
with a minor patch to enable libssh compile under MSVC2010.

I'm not aware of the build you are referring to.

That seems to be a missing function declaration from libssh.h. 
Apparently, something like 
... 
LIBSSH_API ssh_channel ssh_channel_accept_forward(ssh_session session, int
timeout_ms, int *destination_port); 
... 
is missing.

Please let me know if the attached ssh.lib (for compiling) and ssh.dll (for
runtime) are ok.
