Subject:	Re: More problems with Make.

I use the $(subst ...) construct to translate directory delimiters.

In the following snippet, I needed to replace the "\" delimiters with "/" (which is what "gcc" likes) in the environment variable
JAVAHOME (inherited from my CMD DOS-Prompt session). This was necessary to pick up the Java C headers (for some native stuff).

CC=gcc -c -I$(subst \,/,$(JAVAHOME))/include -I$(subst \,/,$(JAVAHOME))/include/win32
