Rename bug in POCC and or POLIB?

[Werner]

If I build a static library in a directory called "fo_test", the output is named "fo_test.lib". So far, so good.

But neither attaching "/Fo other_name" to CCFLAGS nor attaching "/OUT:other_name" helps:

The first alternative--with prefix "/" or "-" and added with/without space/quotes--has no effect.
The second alternative just yields an error.

What do I not understand?
