I believe we do not need to add the other extensions (except for .inf)
to _AC_COMPILER_OBJEXT_REJECT, unless the compiler uses neither `.o' nor
`.obj' for object. `configure' *should* in fact remove the other files
created during its tests.

I don't know a compiler that creates executables with these extensions
(but I haven't been around much in this regard).
OTOH, one of the most valuable assets of Autoconf is the number of very
experienced participants of its mailing list. Let's just wait a few
days, someone may speak up if above assumptions are wrong. :)

Not that I know of. You can always define your own macro, for example
a fixed version with the same name. But that may be very fragile, not
compatible with the next or previous Autoconf, or anything, so I would
not recommend it. Maybe AC_EXEEXT should offer a possibility to
override it.
Updated patch below.
Cheers,
Ralf
