Head file for IRIX 5.1.1.2???

[Long Lee]

 I am trying to compile GRASS 4.1 on an SGI with a
 RS4400 chip and an IRIX 5.1.1.2 operating system.
 Does anyone have a head file for this combination of 
 hardware/software that will result in a sucessful 
 compile? I have tried various implimentations based
 on the SGI IRIS head file found on page 30 of the
 spring 1993 Installation Guide to no avail.
 All help is greatly appreciated.
