Comment 4 for bug 1714265

I generally have no decide to force something, I am just happy for the current capitalization currently, because it is easy to see whether it makes use of pre-processor statements.

You are the expert in autotools, so if you think this is for the better, then fine by me :)

Up till now the philosophy in the build-system was implicit rules which never required a change in the build-system when changing the extension. But if your build-system will use explicit rules, then yes we should convert to a common filename (.F90).

I just felt like commenting ;)
