[9fans] drawterm + gcc + Solaris

[Ish Rattan]

System is SunBlade-100 running Solaris-8.

I tried gcc-3.0.3 (64-bit) to compile drawterm. I saw the error message
shown below. The line in question is
	rune = va_arg(*arg, Rune);
relacing Rune by int does result in successful compilation BUT
drawterm crashes (signal 11). It did compile gcc-2.95.3 (32-bit) compiler
and works.

I don't have enough information to be sure, but my *guess* is that
the variadic-argument function interface changed between release 2.x
and 3.0 of GCC, and whatever support you're using for it wan't done
right.  Make sure the prototypes for such functions are always in
scope, using the ,...) notation, and that the right implementation
of <stdarg.h> is being used for the va_* interface definition.
