So that means that
	TeXLive::TLWinGoo::broadcast_env()
does not return a proper return value. And indeed, reading the code it
doesn't do any proper return value handling.

Siep: anyting we can do here? Return 0|1 for failure|success or similar?
Sorry, I simply cannot understand what is going on in this function with
all the Windows stuff.

If not, I will just drop the |= call.

Best

Norbert
