What about checking whether .gvimrc is sourced or not?
Testing also for has('x11') could be a way to be sure vim is compiled
for x11, and running with an X connection.
Reading the documentation from |.gvimrc|, it seems there are a few other
way to test for the fact you are running with graphics support.
Unless you want to also support vim running in console, and with X-term
support [1], this should do it. Otherwise, what about testing the
options vim was launched with (thanks to a system('ps
-relevant-options')) ?
HTH,
[1] I don't know whether it is relevant or not.
