I saw this on SunSpots and thought I'd post it here (has it already
gone by? I forget.)

Subject: Re: GNU Emacs on the Sun-4
I've built gnu-emacs (18.46) for our new Sun-4, using crt0.c code
from eb@kent-state.UUCP (Eric Benson):
asm(".seg \"text\"");
asm(".global __start");
asm("__start:");
asm("mov 0, %fp");
asm("ld [%sp + 64], %o0");
asm("add %sp, 68, %o1");
asm("sll %o0, 2, %o2");
asm("add %o2, 4, %o2");
asm("add %o1, %o2, %o2");
asm("sethi %hi(_environ), %o3");
asm("st %o2, [%o3+%lo(_environ)]");
asm("andn %sp, 7, %sp");
asm("call _main");
asm("sub %sp, 24, %sp");
asm("call _exit");
asm("nop");
asm("call __exit");
asm("nop");
It builds, and runs, but when find-file is called, crashes with a
segmentation violation. I find that egetenv("HOME") returns a 0, rather
than a string, and the error occurs in strlen'ing the NULL. I suspect
that _environ is not being set correctly. Can you help?
Thanks for any tips.
