autoconf 2.53 configure.lineno problems

[Allan Saddi]

On shells that don't support $LINENO (e.g. FreeBSD's sh), it
appears that configure.lineno isn't being cleaned up. This
causes "make distcheck" to fail when using automake-generated
Makefiles. Shouldn't this be cleaned up somewhere? Like after
configure executes configure.lineno? Or perhaps in the trap/exit
handler, when temporary files are deleted. (Though
configure.lineno would then be deleting itself -- I'm not sure
how bad that would be.)

Any thoughts?

TIA.
