I noticed that Makefile.pre.in uses the value from the environment variable LDFLAGS but not CPPFLAGS. Any reason for this? How did you notice that? For LDFLAGS, Makefile.pre.in has LDFLAGS= @LDFLAGS@ This does not mean that the value from the environment is used. Instead, it means that configure computes the value of LDFLAGS when it generates Makefile.in. For CPPFLAGS, configure has nothing to compute, so Makefile.pre.in just has the static value for CPPFLAGS.

I realize that much. But if you look in configure.in it seems to use the previous value of LDFLAGS every time it is redefined as a base and thus gets its initial value from the environment variable the first time it is tweaked.

Not a big deal, though. I will just use the environment variables in setup.py .
