From b71e56a68384748f2dc712471957b719513508fb Mon Sep 17 00:00:00 2001 From: Vadim Kochan Date: Thu, 18 Apr 2019 08:04:19 +0300 Subject: autoconf: #include when checking for gettext() Some libc implementations like uclibc or musl provides gettext stubs via libintl library but this case is not checked by AC_CHECK_LIB(c, gettext ...) because gcc has gettext as builtin which passess the check. So check it with included libintl.h where gettext may unfold into libintl_gettext which will cause check to fail if libintl_gettext are needed to be linked with -lintl.
