Re: RFA: test for GDB C++ STABS problem

[Michael Elizabeth Chastain <mec@shout.net>]

This patch is approved, with one optional change request.  That is to say,
you can commit it as is, or you can make the change.

The optional change is to add an initialization for "var_in_b"
to a nonzero value such as 100.  That way, the test is less likely 
to succeed by accident.  I tried this and it did not affect the
test results.

Here are my testbed results (native i686-pc-linux-gnu gdb HEAD):

  2.95.3          -gdwarf-2    PASS
  2.96-rh         -gdwarf-2    PASS
  3.0.4           -gdwarf-2    ERROR: process no longer exists
  gcc-3_1-branch  -gdwarf-2    PASS
  HEAD            -gdwarf-2    PASS

As always, I appreciate your essays in the comment section.
