1. GCC doesn't support CMD files
2. It also doesn't need shell variable expansion, or other .bat file
constructs
3. The current method for GCC sets JAMSHELL on the target to "%" so that
the link line will be passed directly to the OS, bypassing .bat file line
length limits. I don't know if there are other limits lurking deeper.
