In my example I did choose to simplify things by naming files like a.c
and a.h.

To accomplish this I had to use touch, but I think that It won't take to
much time. This is my Makefile:
-8<--------------------------------------------------------
all: a-test
%.o: %.c %.h
touch $@
a-test: a.o b.o c.o
gcc -c $(subst .o,.c,$?)
gcc -o $@ a.o b.o c.o
-8<--------------------------------------------------------
So there will be one touch made for every file that needs to be
recompiled, but all files will be recompiled with one call to gcc.
