Yes, that would make sense.  It is odd that 'config.status' has a -d
or --debug option, to do just this, but 'configure' lacks such an
option.  I suppose it should have one.

Fixing this in general won't be trivial, as the trap to remove
temporary files (in _AC_INIT_PREPARE) is established after
configure.lineno is created (in _AS_LINENO_PREPARE).  The two macros
ought to be decoupled as much as possible, and this would couple them

Also, there's a similar problem with config.status and config.status.lineno.

Anybody want to volunteer to write a patch?
