GCC v.2.95.2 Bug Report on Solaris 2.6

[Jackie Zoucha <Jackie dot Zoucha at trw dot com>]

Here is the bug I found; the compiler told me to submit a bug report.
Source code, *.ii and *.s are included (I condensed my code down to a
very simple example that still has the problem). 

The main problem is that I accidentally declared static a variable
that should have been const. A version of gcc on a Linux system gave
me a useful error and pointed me to the problem.
