[kaffe] -C option breaks on non gnu make

[Riccardo]

Hello,

I was checking  the status of the kaffe make system on non-gnu makes. 
Although some makes are known to be very limited, it would be nice if at 
least BSD make and some other know unices makes would work.

It seems that the -C option is not supported by BSD. Here is the debug 
output of a make

Examining BUILD_ENVIRONMENT...modified 16:11:37 Jul 09, 2004...up-to-
date.
Examining all-local...non-existent....PHONY node...out-of-date.

PS: a check in hp-ux make shows it doesn't support -C either.
