-cin doesn't respect -kif

[Kurper]

Steps to reproduce:
1. Write some code.
2. Compile it.
3. Compile again with -cin -kif.

Expected: Since the intermediate files aren't there, it ought to generate them.

Result: Doesn't generate them, since -cin only looks for the .exe.

By intent (and complexity of implementing otherwise) -cin Only determines recompilation on timestamp of exe vs sources,
there is no attempt to ascertain need on changed/new compiler options.

see  cobra -cin foo
and
 Compiler missing up to date checking
and
 compile-if-needed take into account a different -number?

Hops is correct. But I did expand the cobra -help on -compile-if-needed to help clarify its behavior. changeset:2421
