This test program is generated according to gettext.m4.
It's a bug of old version gettext, and it's fixed in gettext-0.14.4.
I modify configure.ac to require gettext-0.14.4, build libvirt
with -Werror, and receive the following error messages:

The following patch can fix the problem:

gettext() returns char *, and we try to convert it to int. The size of pointer
and int is different, and gcc will give a warning. I build it with -Werror, so
the test program can not be built, and NLS is disabled. But We only install
translations when NLS is enabled.
