------- Comment #35 from janis at gcc dot gnu dot org 2009-01-27 18:45 ------- In response to comment #34, the -B option overrides GCC_EXEC_PREFIX and the compiler being tested in the build directory is invoked with -B. GCC_EXEC_PREFIX will only be used to find files that are not in the build directory.
