Pkg xen devel - Jun 2013 - Bug#712376: xen FTBFS with current gcc-4.8

Source: xen
Version: 4.2.1-2
Severity: serious

When trying to build xen in current sid environment, which now uses
gcc-4.8.1, it fails to build:

gcc -O2 -fomit-frame-pointer -m64 -fno-strict-aliasing -std=gnu99 -Wall
-Wstrict-prototypes -Wdeclaration-after-statement -Wno-unused-but-set-variable

This does not happen with gcc-4.7.

(I tried to fix a few other xen-related bugs -- like producing wrong ocaml
libs referring to builddir -- #710650, or missing libssl-dev delendency --
#712366, but now it also fails due to gcc-4.8.  Oh well)

Thanks,
