🚀 go-pugleaf

After compiling emacs 18.55 on a Sun Sparc machine running SunOS 4.1
I discovered that "M-x shell" doesn't work. The only error message
reported is
	Process shell exited abnormally with code 1
I have applied all three of the patches that look like they might apply
to my problem in the FAQ list:
	1) #define SYSTEM_MALLOC
	2) patch to alloc.c redeclaring staticvec
	3) adding setpgrp call in process.c
I compiled using the Sun C compiler and with GCC and tried both with
and without optimization.

Any help would be appreciated. Thanks for your time.
