Well, I doubt I have a fix for you right now, but I'll post what I have
found for the benefit of others. I was poking through the source to GNU
make tonight for another reason and as I read through the Makefile I saw
something that brought back your problem from the depths of my subconscious.
There is apparently a compile-time DEFINE in GNU make called "NO_MINUS_C_MINUS
_O". I don't know what happens if you define it against the grain of the way
your C compiler works (since I've never personally compiled GNU make) but the
example line they show as for whether or not to -D that constant is:
gcc -c foo.c -o foo.o, which looks hauntingly similar to the one which you
listed above (except for the case of the C, which you probably just missed
while pulling it from your brain).
I just wanted to make sure you were aware of the existence of that
constant. If you weren't aware of it, I'd see if you've been defining the
constant during your recent compiles of make, and do the opposite thing. :)
I hope this was of some help to you.
