1.75 test suite failures with Sun C compiler

With the Sun C compiler, I get the following testsuite failures on
Solaris 2.5.1, 2.6, 7, 8, and 9/SPARC:

Simple GLR Calculator.

Similar failures for Tru64 UNIX 5.1 and the Compaq C compiler, for
IRIX 6.5 and the IRIX C compiler, for HP-UX 10.20, 11.00, 11i and the
HP C compiler.
