RFC: Patch to change what sets the is_win9x in riched20/tests

[James McKenzie]

All:

Upon examining other test code that creates a variable called is_win9x, 
I realized that using get_version and comparing it to a fixed value may 
not be best for the riched20 tests and have attached a proposed change 
to how this variable is set.  It uses a called function, lstrcmpW and if 
it does not exist, the variable is set to a false value.  This change 
has been tested on the testbot for 
Windows95/98/98SE/2K/2K3/XP/XP_64/Vista/Vista64/Win7/Win7_64 and no 
discrepancies were found.

Comments on this patch are appreciated.  I would like to submit this for 
inclusion into the Wine code base on Friday.
