changed, otherwise you could just copy the old implementation if you are
upgrading just to a similar version of Jemalloc.
#### Updating/upgrading jemalloc
The jemalloc directory is pulled as a subtee from the upstream jemalloc github repo. To update it you should run from the project root:
1. `git subtree pull --prefix deps/jemalloc https://github.com/jemalloc/jemalloc.git <version-tag> --squash`<br>
This should hopefully merge the local changes into the new version.
2. In case any conflicts arise (due to our changes) you'll need to resolve them and commit.
3. Reconfigure jemalloc:<br>
```sh
rm deps/jemalloc/VERSION deps/jemalloc/configure
cd deps/jemalloc
./autogen.sh --with-version=<version-tag>-0-g0
```
4. Update jemalloc's version in `deps/Makefile`: search for "`--with-version=<old-version-tag>-0-g0`" and update it accordingly.
5. Commit the changes (VERSION,configure,Makefile).

1. Makefile is modified to allow a different compiler than GCC.
2. We have the implementation source code, and directly link to the following external libraries: `lua_cjson.o`, `lua_struct.o`, `lua_cmsgpack.o` and `lua_bit.o`.
3. There is a security fix in `ldo.c`, line 498: The check for `LUA_SIGNATURE[0]` is removed in order to avoid direct bytecode execution.
