Message:

refs #118 Added flag to configure '--enable-debug'. If this flag is not used
(default) CXXFLAFS and CPPFLAGS are set in production mode, i.e.
CPPFLAGS="-DHAVE_INLINE=1 -DNDEBUG -DGSL_RANGE_CHECK_OFF"
CXXFLAGS="-Wall -pedantic -O3"
is used. On the other hand if you use configure --enable-debug you will get
CPPFLAGS="-DHAVE_INLINE=1"
CXXFLAGS="-Wall -pedantic -g -O".

NOTE since this is a change of configure.ac you need to run bootstrap.
