[Swig-devel] luatypemaps.swg creating multiple definitions of %fragment

[Number C. <num...@nt...>]

In version 2.0.0, line 94 of Lib/lua/luatypemaps.swg declares a 
%fragment for SWIG_lua_isnilstring, but doesn't prefix the function with 
SWIGINTERN; this results in multiple definitions of the same externally 
visible function when multiple %modules are linked in.

The solution is just to add SWIGINTERN.

Please find patch attached.
