I don't see anything gettext related in there. What I see is:

/usr/bin/gcc -Wp,-MD,tools/kconfig/.zconf.tab.o.d -Wall -Werror -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -Wdeclaration-after-statement     -DCURSES_LOC="<ncurses.h>" -DLOCALE -DKBUILD_NO_NLS -Itools/kconfig -c -o tools/kconfig/zconf.tab.o tools/kconfig/zconf.tab.c
In file included from tools/kconfig/zconf.tab.c:2576:0:
tools/kconfig/confdata.c: In function 'conf_set_all_new_symbols':
tools/kconfig/confdata.c:1167:2: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]
cc1: all warnings being treated as errors

I.e, the built-in kconfig copy of the Xen sources doesn't build with
the host compiler on this machine. All issues appear on gcc20, where
the host compiler is gcc 4.7.

I guess the easiest fix here is to remove -Werror from the compile
command line. Can you look at how to do this inside the Xen source code?

Thanks!

Thomas
