Perhaps vim is also not using real tabs... I haven't used it for a
while.  If you know how to use debug, you could debug the makefile and
find out whether it really does have real tabs, or spaces.  IIRC in
the Win95 DOS Edit you can insert real tabs by typing Ctrl-P Ctrl-I.
It's flaky, though; if you do too much editing it can change them all
back into spaces again. :(

Note that you can get around this problem to some extent by leaving
out the commands in your makefile ;).  Make already knows how to do
most of what you want it to do... you can rewrite your makefile like
this:

--- begin makefile ---
# Tell Make what compiler to use
CC = gcc

# Tell Make what flags to pass for C compilation (you didn't use any
# but this is how you pass them)
CFLAGS = -O2 -Wall -g

# The following rule runs the value of `CC'. $@ expands to the target
# name (program.exe in this case), and $^ expands to the complete
# dependency list (mainsrc.o printer.o header.o in this case)

program.exe: mainsrc.o printer.o header.o
	$(CC) -o $@ $^

# The following rules don't have commands given.  Make will look
# through its internal database to decide what to do to them.

mainsrc.o: mainsrc.c printer.h header.h

printer.o: printer.c printer.h

header.o: header.c header.h

--- end makefile ---

Now it only has one tab in it -- less opportunity for Edit to corrupt
it ;).

Also a brief comment on your C code... In mainsrc.c you have:

: void main(void) {

This is bad.  The `main' function must return an integer -- you should
declare it like this:

int main (void) {

and you should put in a `return' statement before the closing brace.

And finally, your `header.c' and `printer.c' files should have
`#include <stdio.h>', since they use printf.
