agreed.  Using (error "errorstring") in the scheme code you can 
make gnetlist error out with a non-zero error code, but I'm not sure
how to signal to gnetlist that there are warnings and it should return
that.

What do you think of having a command line option which prevents warnings
from giving an error code?

print the warnings from gnetlist directly or detect them in the makefile?
