The problem is, again, that the list of -fxxx options that, if
disabled, will make the program much easier to debug, is not known
except to the few GCC developers.  So I don't think we know what to
put in aclocal.

If you mean to build a configure-time test that will try each -fxxx
option and somehow establish whether it does or does not disrupt
debugging, then I think this is too large a job, and it will
constantly bitrot due to -fxxx options being removed and added as GCC
is developed.

Or maybe you mean something else?
