Re: X86 GIT GCC 5 compilation warning

[Enrico Mioso <mrkiko.rs@gmail.com>]

Hi guys.
First of all - thank you for the discussion, and everything.

I am on arch linux, regularly upgraded.
$ as --version

This assembler was configured for a target of `i686-pc-linux-gnu'.

I attach you the PKGBUILD file - the brilliant Arch team made the entire system so it's fairly easy to understand it.
