When applied, the above patch will allow opennx to use vcxsrv.  This prevents issue when running x2go from the same window box.   

I still can not get the full project to build.  I have a work around that allows me to work for now. 
I need to document the patches so I will have a full write up when I get a chance.
for now, If it put the pulse header files in the package path. I can make opennx.exe and tracelog.exe.

make opennx.exe

to fix the following:
