- Split current usage of CXXFLAGS into the conventional CPPFLAGS CXXFLAGS and LDFLAGS
- Split current usage of CFLAGS into the conventional CPPFLAGS CFLAGS and LDFLAGS
- This restores 'make whatever CXXFLAGS=-g' which stopped working during
the recently added suppport for out of source builds.
- LDFLAGS is currently empty, but is there for future use
- Examples/Makefile.in rules use SRCDIR as the relative source directory
- ./config.status replicates Examples/ source directory tree in build
directory, and copies each Makefile to build directory, prefixed with
a header which sets SRCDIR to source directory
- Examples/test-suite/.../Makefile.in set SRCDIR from Autoconf-set srcdir
- Examples/test-suite/errors/Makefile.in needs to filter out source
directory from SWIG error messages
- Lua: embedded interpreters are passed location of run-time test
- Python: copy run-time scripts to build directory because of 2to3
conversion; import_packages example copies __init__.py from source
directory; test-suite sets SCRIPTDIR to location of run-time tests
- Javascript: binding.gyp renamed to binding.gyp.in so that $srcdir
can be substituted with SRCDIR; removed './' from require() statements
so that NODE_PATH can be used to point Node.js to build directory
