And when linking (despite the Cxxxx code, I use /LTCG) I get this warning:
...\lua-5.2.2\src\loadlib.c(187) : warning C4700: uninitialized local
variable 'buffer' used

Let us see:
 char buffer[128];
 if (FormatMessageA(FORMAT_MESSAGE_IGNORE_INSERTS | FORMAT_MESSAGE_FROM_SYSTEM,
 NULL, error, 0, buffer, sizeof(buffer)/sizeof(char), NULL))
 lua_pushstring(L, buffer);
MS documentation says 'buffer' is an _Out_ parameter [1]. What can we do?

Generally, you can rid Visual Studio of this error by doing something like:
 char buffer[128];
+ buffer[0] = 0;
 if (FormatMessageA(FORMAT_MESSAGE_IGNORE_INSERTS | FORMAT_MESSAGE_FROM_SYSTEM,
-Josh
