Dear Maintainer,
While working on the “reproducible builds” effort [1], we have noticed
that 'freefem++' could not be built reproducibly.
The attached patch fixes the order in which files are included in the
edp files, and honours SOURCE_DATE_EPOCH [2] when using the build date.
Once applied, freefem++ can be built reproducibly in our current
experimental framework.
Regards,
Alexis Bienvenüe.
