I have it too (precisely, libgcc_s_dw2-1.dll). If I put it in LuaTeX's 
folder, along with another one which is also missing, and can be found 
in MinGW/bin too, namely libstdc++-6.dll, then LuaTeX works.

It's has if there missed a link toward those dll, which LuaTeX should 
find by itself (as I've repeated several times, I'm ignorant on such 
things, so I might be saying pure nonsense).
