------- Comment #53 from janis at gcc dot gnu dot org 2009-02-09 17:22 ------- Rob, you don't seem to understand that setting GCC_EXEC_PREFIX does NOT cause the tests to use GCC files from the install tree. The test framework explicitly uses -B options to override GCC_EXEC_PREFIX, so the only effect of the variable is to find non-GCC files in the install tree.
