Compiling is ok now - even without --with-threads. But unfortunately
I get the same oops as on ix86 (which I'll try to debug on ix86 as
debugging in IRIX doesnt really work here due to pthreads issues):

(gdb) bt
#0  0x0 in ?? ()
#1  0x40ad064 in scm_shell (argc=268618800, argv=0x0) at script.c:647
Cannot access memory at address 0x2c

(of course this is not very helpful...)

I suspect I'm doing something wrong here - the code I use for testing
is GLAME which you can get via CVS at
cvs -z3 -d:pserver:address@hidden:/cvsroot/glame co
for the cvs password just press ENTER.

The following diff is applied to use the new scm_init stuff (for
relevant startup code follow src/cglame.c to src/glmid/glmid.c -
that should be all). Umm, cannot get access to the cvs at the
moment... hopefully this will be fixed soon. If not I can send
you the relevant files privately.
