AC_INIT([libgim], [0.1.0], [danny@nerdcruft.net])
## Explicitly set an empty CXXFLAGS if not present to prevent AC_PROG_CXX from
## generating a default -O2. This allows us to manually select -O0 when
## debugging is enabled.

## thus overriding any variables that both set (specifically we're concerned
## about optimisation flags).
