Re: lua.h and c++

["Michael Newberry" <mnewberry@...>]

Hi,

Sorry not to menion it here earlier, but I've been doing the same thing and
everything has always worked as expected. Each time I've installed a new
release, I've had to go into the source and add the cplusplus definition. It
would be nice it it shipped that way.
