But now you undo the CPPFLAGS as defined in the makefile. I didn't
know how to add to the CFLAGS from the command line, but found a
solution here:

http://theory.uwinnipeg.ca/localfiles/infofiles/make/make_66.html#SEC65

It requires a small adaptation to the makefile. Instead of:

CFLAGS = ....

comes:

override CFLAGS += .....

Now you can add to CFLAGS from the command line, like so:

make CFLAGS="-DPD_FLOAT_PRECISION=64"

Note that the CFLAGS in the makefile now have precedence and you can
only add to it from the command line, not override it.
