Porting code gives "unknown size" C compiler error

[David P. Lithgow]

	To any who've ported C code from Ultrix/VAX to Ultrix/MIPS,
I'm getting a compiler error, and a friend of mine says that
it is a known error, but I can't find the soultion anywhere in the
Ultrix V3.0, V3.1C, V3.1D, or V4.0 documentation, or the
"Release Notes for RISC Processors".

	Here's the error:

# make prog
cc -O -c prog.c
ccom: Error: prog.c line 583: unknown size
	struct exec execb;
      -------------------^
...
...
... more errors due to above error
...
*** error code 1

Stop.
#
	This make works without problem under Vax/Ultrix V3.0, but
fails with the above error under MIPS/Ultrix V3.1D.

	I've rtfm-ed to no avail - can anyone help?  Is this a
known problem with a known workaround?
