Re: Cleanup on AC_MSG_ERROR

[Akim Demaille]

| Hello!
| AC_MSG_ERROR is almost always called "unexpectedly", i.e. inside tests, so 
it's
| a good idea to clean temporary files before exiting.

Why not a better trap?

| Temporary files shouldn't be used for debugging. Either config.log should be
| used, or (in very hard cases) configure should be edited to copy temporary 
files
| at a known point. So please don't worry about too many rm's - they will never
| have to be conditional.

I agree with the point, but I still would prefer to understand why
trap did not rm those files.  That's the bug to kill imho.
