Problems with 18.51 on SGI IRIS 4D

[Eric A. Pearce]

 I'm trying to compile emacs 18.51 for an SGI Iris 4D running
 "IRIX System V Release 4D1-3.13809261636"
 
 (I used "m-iris4d.h" and "s-iris3-6.h")

 Since it does not have a "/usr/lib/crt0.o", I tried doing the following:
 
 "/usr/lib/crt0.o" changed to "crt0.o" for START_FILES in src/m-iris4d.h

	ld:
	Warning: data_start: multiply defined
	Undefined:
	sigblock
	start
	*** Error code 1

	Stop.
	*** Error code 1

	Stop.

 "/usr/lib/crt0.o" changed to "/usr/lib/crt1.o" for START_FILES in 
 src/m-iris4d.h

	ld:
	Undefined:
	sigblock
	start
	*** Error code 1

	Stop.
	*** Error code 1

	Stop.
	*** Error code 1

Stop.

 Any ideas?
