I've been compiling beta4 on a Sparcstation 1 using gcc.

1) builtin_driver_args in m3.c writes into its argument, which
can be a string constant.  This requires the gcc
-fwritable-strings flag.  Are writable strings required for the
target code as well?

2) I've been getting nondeterministic runtime errors from the m3
compiler.  Anyone else see this?  They go away if you retry the
compile.  For example:

.ROOT/system/driver/m3.local -D.ROOT/libs/Xlib/Interfaces:.ROOT/libs/Xt/Interfac
es:.ROOT/libs/Xaw/Interfaces -g -c xboxes.m3
M3 runtime error: Value out of range
Program .ROOT/system/compiler/m3compiler got fatal signal 3.
*** Error code 1

I also got the same error with Xlib/X.i3.  Anyone else see this?
