I remember having this bug for quite some time, but I discovered an interesting issue. `dmd app.d -I.` causes an `Error: unrecognized file extension `. Same thing on `dmd app.d -I=.`. This error occurs ONLY in Powershell. The Command Prompt does not get this error. I have a faint feeling that this error has already occurred with me ldc2.

Hmm, it seems that powershell, for some reason, splits the dot from what is preceeding it so when it calls dmd it sees -I and . as 2 separate arguments. Unforuntately, this is not something that can be fixed inside the compiler, but in powershell. For more information, see https://stackoverflow.com/questions/25979247/why-powershell-splits-arguments-at-dots-in-some-cases

Do you think that having a mention about this somewhere would be valid?

I don't think it's the job of the compiler spec to document the various quirks of different CLI implementations.
