GNU make doesn't pick up changes

It's been a while since I had to write a Makefile, but I've managed to clobber this together:

Code:

SRC=module1.c module2.c
OBJS=$(SRC:%.c=%.o)
HDR=include1.h include2.h

CC=gcc
CFLAGS=-Wall -ggdb -D_XOPEN_SOURCE -I. -ansi

all: program

program: $(OBJS)
        $(CC) $(CFLAGS) -o $@ $(OBJS)

.o: $(@:%.o=%.c) $(HDR)
        $(CC) $(CFLAGS) -c $<

clean:
        rm -f program $(OBJS)

It works for the most part, except when a change in one of the includes happens, result in make telling me "nothing to do".

Code:

$ make
gcc -Wall -ggdb -D_XOPEN_SOURCE -I. -ansi   -c -o module1.o module1.c
gcc -Wall -ggdb -D_XOPEN_SOURCE -I. -ansi   -c -o module2.o module2.c
gcc -Wall -ggdb -D_XOPEN_SOURCE -I. -ansi -o program module1.o module2.o
$ touch include1.h
$ touch include2.h
$ make
make: Nothing to be done for `all'.
$ touch module1.c
$ make
gcc -Wall -ggdb -D_XOPEN_SOURCE -I. -ansi   -c -o module1.o module1.c
gcc -Wall -ggdb -D_XOPEN_SOURCE -I. -ansi -o program module1.o module2.o
$

Both include?.h files are used in both module?.c files. I probably screwed up the prerequisite part of the target definition, but for the love of the FSM, I can't find it.

All files reside on a ext3 LV, without any special time-keeping options altered.

Any help would be greatly appreciated.

xmscrollvisible

XmScrollVisible(library call)											     XmScrollVisible(library call)

NAME

       XmScrollVisible -- A ScrolledWindow function that makes an invisible
	descendant of a ScrolledWindow work area visible

SYNOPSIS

       #include <Xm/ScrolledW.h>
       void XmScrollVisible(
       Widget scrollw_widget,
       Widget widget,
       Dimension left_right_margin,
       Dimension top_bottom_margin);

DESCRIPTION

       XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function re-
       positions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location relative
       to  the	viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the
       ScrolledWindow widget be set to XmAUTOMATIC.

       scrollw_widget
		 Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant.

       widget	 Specifies the ID of the widget to be made visible.

       left_right_margin
		 Specifies the margin to establish between the left or right edge of the widget and the associated edge  of  the  viewport.   This
		 margin is established only if the widget must be moved horizontally to make it visible.

       top_bottom_margin
		 Specifies  the  margin  to  establish between the top or bottom edge of the widget and the associated edge of the viewport.  This
		 margin is established only if the widget must be moved vertically to make it visible.

       For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3)
