All kind of flags are hard-coded in linux.cf in nx-X11/cf/ (I think).  
You may know imake better then I do. If you could take another look at  
it, that would be awesome.

Note: LDFLAGS appear to be named LDOPTIONS in nx-X11.

Note, that nxcomp, nxcompshad and nxcompext are configured and built  
from within nx-X11/programs/Xserver/Makefile.in (IIRC, might be the  
Makfile.in one level up). So the nx* builds are prepared by imake. I  
guess the only way to address it is to teach imake to let through  
*FLAGS.

The nx-X11 build process is a bummer..., I agree with that. Any help  
and improvement is really appreciated.

Greets + HELP!!! + Arggghhh...,
Mike
