You are correct, I misspoke.
Lua will compile as either ANSI C or as C++. By default most compilers
determine the form to compile based on the extension - .c is treated as
ANSI C. However, you can override this with various command line
switches (e.g. /TP with MSVC).
You just have to be very careful that you're aware what's going on and
that you're consistent.
An error I've made more than once was doing this:
In a C++ file that uses Lua, but forgetting that I was compiling Lua as
C++. Or, conversely, compiling Lua as C++ and accidentally putting the
"extern C" around the include statement from another source file.
