Well ,

if the DOS make utility is the same as all the UNIX types then you
should
be able to set enviroment variables inside the Make file.

When I usually compile a program (haven't done many for PSX yet .. uni
is
in the way =( )  I set 2 variables, one called SOURCE , the other obj

i.e

SOURCE	=	source.cpp
OBJ	=	source.o

EXE	=	source

all: ${EXE}

${EXE} : ${OBJ}
	${GCC}	-o ${EXE} ${OBJ}

${OBJ} : ${SOURCE}
	${GCC}	-c ${OBJ} ${SOURCE}

For a fact I know that this works on UNIX. But I haven't had much
experience
with DOS make.

Anyway ... you can set any variable really. But there are some which
Make usually
likes to reserve.... can't list all of them.

The GCC variable is the compiler command line exe call.

If you need any more help drop me an email
