A newly detected buggy behavior with c++ compilers

[stefanos82]

@edubart I have compiled the latest changes after you reported the bug fix in #279 (thank you for that!), I have decided to check all my files, one my one.

Remember this gist of yours, where you demonstrate Celeste version implemented in Nelua?

Well, this one throws some interesting error messages; seems like behind the scenes, you are using the word this as a parameter name and both GCC (g++) and Clang (clang++) stop the compilation due to the usage of this keyword.

Makes sense, there are a lot of C++ reserved keywords that need to be listed to avoid problems like this at https://github.com/edubart/nelua-lang/blob/master/lualib/nelua/cdefs.lua#L649 . I've listed all keywords relevant C11, but indeed words related to C++ must be added there, will try to do this later.

No worries, take your time.
