As of version 3.1, gawk itself has been internationalized
using the GNU gettext package.
(GNU gettext is described in
complete detail in
GNU gettext tools.)
As of this writing, the latest version of GNU gettext is
version 0.11.5.
If a translation of gawk's messages exists, then gawk produces usage messages, warnings, and fatal errors in the local language.
On systems that do not use version 2 (or later) of the GNU C library, you should configure gawk with the --with-included-gettext option before compiling and installing it. See Additional Configuration Options, for more information.
