Well, you could try "info make" if you have downloaded and installed the
info thingy. And also remember not to use the DOS Edit program, because
make needs real tabs (atleast it doesn't work for me otherwise) and Dos
Edit doesn't support that. 

The very basic structure would be something like:

all: <target>
        <commands to make target>

<file1>: <file1dependencies>
        <commands to make file1>

<file2>: <file2dependencies>
        <commands to make file2>

Say I have a file named runme.exe that would be created from two object
files called main.o and extra.o which would be made of main.c and extra.c,
where main.c locally includes main.h and extra.c includes both main.h and
extra.h, the makefile would look something like this:

all: runme.exe
        gcc -o runme.exe main.o extra.o

extra.o: main.h extra.h
        gcc -c -o extra.o extra.c

main.o: extra.h
        gcc -c -o main.o main.c

And remember to use REAL tabs. 

(I haven't tested the makefile example above, but I think it would work)
