Lz4: v1.7.3 build fails with GCC 4.4.x (ie: CentOS 6.x)

[totaam]

It would be nice to continue to support those older distributions (I don't like it, but I have to..).

Here's the build failure:

In file included from ../lib/lz4.c:92:

FYI: builds succeeded on all current and future versions of Fedora (up to gcc 6.2.1), openSUSE, CentOS 7.x, etc.
I did see an rpm lint warning though:

*** WARNING: identical binaries are copied, not linked:
        /usr/bin/lz4c
   and  /usr/src/tmp/BUILDROOT/lz4-1.7.3-1.fc23.x86_64/usr/bin/lz4

Mmmh, deprecated("message") is supposed to be a feature of gcc 4.x,
but if does not work for gcc 4.4, then I clearly missed something.

[Cyan4973]

Indeed, my fault, I misinterpreted,
I though it was introduced within gcc 4.05,
but it was in fact introduced in gcc 4.5.
Hence problem with 4.4...

To be fixed

Latest update in dev branch should fix the reported issue
