Bug description

ocamlc -use-runtime without -custom simply embeds the value as the path to the runtime interpreter at the beginning of the file. However, it doesn't prepend '#!', and as a result the executables can't be ran, at least not without directly invoking ocamlrun (which sort of defeats the point of using -use-runtime). It's possible to pass a path starting with #!, but this fails when Symtable tries to autodetect the primitive list. This can be worked around using -use-prims, but then Bytelink tries to absolutize a path starting with #! and breaks it.

This couldn't possibly ever work, and based on git blame, it was never changed since 2001 (!) Am I the first one using it?..

It worked on MacOS 9 with MPW, which didn't need the #!
As far as I know it was never even tried on anything else.

Feel free to write a patch.

@gasche, I've discovered this patch requires a bootstrap in order to be effective for the compiler itself. Could you bootstrap 4.02?
