Force "static" variables to be in global memory (grischka-2005-09-25 bugfix 5).
This patch was originally posted in grischka's 2005-09-25 email as a
"required fix" 5 to compile gcc 2.95. It was tweaked by
David A. Wheeler to merge the test case into the standard tcc test suite.
The test case was enhanced to ensure that multiple different static variables
with the same local name were mapped to different memory locations
(if they originated from different scopes).
