Synopsis: C code for expanded local generates warnings

Description

The C code for a routine that references a constant STRING attribute
of a local that is of an expanded type generates warnings:

"../E1/estructure.h", line 39: warning: zero or negative subscript

Note that the generated C code is not ISO C according to Sun Studio 12
(won't compile with -Xc flag to C compiler).

To Reproduce

Freeze with attached classes and config file.
Compile C code, using Sun Studio 12 as the C compiler.
Generates "zero or negative subscript" warning.

It should be fixed in rev#76592.

I've added test#ccomp081 to show the problem which will only fail on platforms where the C compiler refuses our generated C code.
