Hello!  AX_BOOST_PYTHON does not use quotes when setting CPPFLAGS, which can cause problems if CPPFLAGS is already defined to something.  For example:

1) Imagine CPPFLAGS starts as "-DTEST=1 -DTEST=2"
2) "CPPFLAGS_SAVE=$CPPFLAGS" will expand to "CPPFLAGS_SAVE=-DTEST=1 -DTEST=2" which will try to run the program "-DTEST=2" with a temporary CPPFLAG_SAVE environment variable.

1) Imagine CPPFLAGS starts as "-DTEST=1"
2) You'll get past the previous problem because CPPFLAGS is only one word.
3) But "CPPFLAGS=-I$PYTHON_INCLUDE_DIR $CPPFLAGS" will expand to something like "CPPFLAGS=-I/usr/include/python2.7 -DTEST=1" and you hit the same issue again.  The program "-DTEST=1" will not be found.

The attached patch fixes AX_BOOST_PYTHON for me.  A quick grep showed that some other macros might be affected too, so you might want to do a general check.
