RE: Probably stupid make question
Well, this is just ducky. I'm posting this so it goes in the archives and maybe saves someone else a LOT of heartache.
Batch files treat incoming, unquoted equals signs as spaces!
For the cross-compiling I'm doing, I have to use a .BAT file (or equivalent), because the cross-compiler is two-stage -- it generates assembler from C, then must assemble that.
Thus my batch file to do the compiles gets invoked correctly as (say):
-DSOMETHING=AVALUE Banana.c
but the batch file sees this as:
-DSOMETHING AVALUE Banana.c
Quick, someone build me a time machine so I can go back and kill whoever implemented THAT (I know, get in line...)!

As the make maintainer, let me say: What he said.
