Looking at the most probable source of this message (in src/lsp/cmdline.lsp)
I am a bit puzzled by the situation...

Please, reassure me on the exact version of MKCL you're using: 1.1.10-???

And how do you invoke MKCL to get this result (command line arguments)?
Do you have handy a small scenario to reproduce this problem?

Looks more like a ill-advised feature than a bug, that I can surely
fix/improve
to better satisfaction. I am investigating...

Not sure yet. I'll tell you with the fix.
