Yes, even running vi or csh in Ultrix (in simh pdp11) produced message : 
too big. After setting cpu to 3072K it worked(setting to 4096 K hanged 
the system BTW).
Cross compilation has also this advantage , that You have better editors 
to Your disposal and You can work faster.
Well native cc seems to be good enough, using pdp11 in emulator we have 
anyway only hobbyst license .
