I notice you have a commented-out section at the bottom:

# How do I compile this file with more compiler optimization?
#md5.o: md5.cpp
#	g++	-o md5.o md5.cpp -O3 -funroll-loops -fexpensive-optimizations -fstrength-reduce -Wall -g -c	

What you could try is giving an attribute to the md5.cpp file to use
different CFLAGS:

	:attr {var_CFLAGS = $CFLAGS -O3 -funroll-loops -fexpensive-optimizations -fstrength-reduce -Wall -g} md5.cpp

The trick is that "var_*" attributes are used for the variables used to
compile a specific file.  Thus when md5.cpp has the attribute
"var_CFLAGS", the value of "CFLAGS" will get the value of this attribute
for a dependency where this file is used as a source.

To avoid it is used for all files, you need to change your dependencies
to be on the ".o" files instead of the ".cpp" files.  The automatic
mechanisms should be able to find out how to make the ".o" file from the
".cpp" file.

I didn't verify this actually works!
