	I do not have experience with NCAR V3.0, just versions 1 and 2. I have
had experience installing older version of NCAR on numerous systems for
about 8 years. These older versions were FORTRAN based not C based, so I have
no real experience at all installing version 3.0, but I may be able to help a 
little anyway.

	Remove all defines for sprintf in the code by commenting them out.
They are already pre-defined for you in IRIX.  I have run into this problem
before when I was installing the Utah Raster Toolkit and other software.  In 
general, when you get a re-declaration error for a "standard" UNIX function
you should comment out the offending definition.

You are mostly correct in your modifications to the compile line.
 (someone please correct me if I am wrong but...)

     cc -DSYSV -I/usr/include/bsd -O -I../../include -c intermed.c -lbsd
  
Should be a more general compilation statement when using BSD functions.
The -lbsd tells the linker to link with the bsd libraries.  It is not
necessary when you compile with the -c option, which tells the compiler
not to invoke the linker.
	In general, when compiling with the 
-I/usr/include/bsd option, including the -lbsd option at the end of the 
compilation statement is a good idea that is harmless when it is not needed
but is VITAL when it is needed.
