I believe every static approach is doomed to fail: why not just add a configure test like this: * first check if the configured assembler can assemble a trivial .stabs line * if this fails, try again if it works with -Q added * if this fails, too, disable both DBX_DEBUGGING_INFO and remove DBX_DEBUG from PREFERRED_DEBUGGING_TYPE This should allow us to support Stabs while possible, but reject the corresponding options once the assembler cannot handle them.
