Both versions of IMMEDIATE functions have been removed.

Before this patch, we'd been calling img_format twice, the first time
through the IMMEDIATE to get an appropriate string and the second time
to print that string. There's no more need for that. Therefore, calls to
IMMEDIATE are removed, and now we're directly printing the integer
values instead.

Yes. The problem here is nobody wants to maintain this code, but we
inherited it. IIUC this series doesn't make it worst, it just remove
the C++ dependency on UNIX-based hosts.

Well since I merged I already prepared some patches to fix this.
