I avoid gettext 100% in my uClibc env by using the following stub
macros.


uClibc env.d # cat /usr/include/libintl.h 
#ifndef _LIBINTL_H
#define _LIBINTL_H      1

#include <features.h>

#if defined(__UCLIBC__) && !defined(__UCLIBC_HAS_GETTEXT_AWARENESS__)
/* Stubs for gettext/locale bullshit... */
#undef gettext
#undef dgettext
#undef dcgettext
#undef ngettext
#undef dngettext
#undef dcngettext
#undef textdomain
#undef bindtextdomain
#undef bind_textdomain_codeset
/* this fucker seems to be installed  in /usr/include/locale.h */
/* #undef setlocale */
#undef _
#undef N_

#define gettext(String) (String)
#define dgettext(Domain, String) (String)
#define dcgettext(Domain, String, Type) (String)
#define ngettext(Singular, Plural, Count) ((Count) == 1 ? (const char *)
(Singular) : (const char *) (Plural))
#define dngettext(Domain, Singular, Plural, Count) ((Count) == 1 ?
(const char *) (Singular) : (const char *) (Plural))
#define dcngettext(Domain, Singular, Plural, Count, Category) ((Count)
== 1 ? (const char *) (Singular) : (const char *) (Plural))
#define dgettext(Domain, String) (String)
#define dcgettext(Domain, String, Type) (String)

#ifndef _LOCALE_H
/* #define setlocale(Category, Locale) ((char *)NULL) */
#endif

#define bindtextdomain(Domain, Directory) (Domain)
#define bind_textdomain_codeset(Domain, Codeset)
#define textdomain(String)

#define _(String) (String)
#define N_(String) (String)

#endif  /* GETTEXT */
#endif  /* _LIBINTL_H */
