Dear Maintainer,

While working on the `€œreproducible builds'€ effort [1], we have noticed
that 'tin' could not be built reproducibly.

Since LC_ALL overwrites the LC_TIME value, the cpp_reprtime script
output is locale-dependent. This could be fixed adding a LC_ALL=C
definition, but as gcc now supports the SOURCE_DATE_EPOCH environment
variable [2] to set the __DATE__ value, I think the best option is to
drop cpp_reprtime -- see attached patch.

Once applied, tin can be built reproducibly in our current
experimental framework.

Regards,
Alexis Bienvenüe.
