Has anyone gotten test_math.a to run on a Sun4/OS 4.1 using VADS 6.0 ?

Has anyone gotten test_math.a to run on a Sun4/OS 4.1 using VADS 6.0 ?

I can compile with the following warnings:

So I ignore the warnings with the -w, and link with the generic math
routines. Then the crash occurs when I run:

test_math_functions

Could someone please refer me to where these "declare" segments are
explained in the LRM?

(Yes, I'm quite sure this is an FAQ, but...)

Have a look at section 5.6, "Block Statements"
