I do not know specifically whether config.status.lineno is created on any  
8.3 platforms.  I was just asking out of general curiosity since it struck me  
as inconsistent that it unconditionally uses this non-8.3-conformant name  
whereas the rest of Autoconf tries to cater to 8.3 platforms by providing  
alternate mechanisms for dealing with those platforms (even if those  
mechanisms are not used by default).  You are probably right about DJGPP  
using Bash, so it may not be an issue in actual practice.  (Although this  
does not mean that we shouldn't fix it.)

Exactly.  Even though Autoconf uses non-8.3 names by default, it still tries  
to cater to 8.3 platforms by providing alternate mechanisms for dealing  
those platforms; and these alternate mechanisms can be utilized/enabled as
