Works for me. A different but minor issue appeared when building 
for mingw. When building after changing a single file, make fails 
because gcc -shared is being used as AR and the $? is incorrect 
when used that way. Only mingw seems to be built this way.

Make output:

$ make mingw
cd src && make mingw
make[1]: Entering directory `/home/khman/lua/lua-5.2.0/src'
make "LUA_A=lua52.dll" "LUA_T=lua.exe" \
        "AR=gcc -shared -o" "RANLIB=strip --strip-unneeded" \
        "SYSCFLAGS=-DLUA_BUILD_AS_DLL" "SYSLIBS=" "SYSLDFLAGS=-s" 
lua.exe
make[2]: Entering directory `/home/khman/lua/lua-5.2.0/src'
gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_BUILD_AS_DLL    -c -o llex.o 
llex.c
gcc -shared -o lua52.dll llex.o
llex.o:llex.c:(.text+0x1f): undefined reference to `luaS_new'
llex.o:llex.c:(.text+0x4e): undefined reference to `luai_ctype_'
llex.o:llex.c:(.text+0x68): undefined reference to `luaO_pushfstring'
... and so on.
