Gtk building error: 'builtin_icons' undeclared

Hello. While cross compiling an old gtk, I am confronted with this error message:

gtkicontheme.c: In function ‘_gtk_icon_theme_ensure_builtin_cache’:
gtkicontheme.c:1151:54: error: ‘builtin_icons’ undeclared (first use in this function)
_builtin_cache = _gtk_icon_cache_new ((gchar *)builtin_icons);

Once I build the same Gtk without cross compiling. However, there I was using libtiff, while here I am passing “–without-libtiff” to configure. Might this bet the source of the error?

Problem solved changing builtin_icons to icon_theme_builtin_icons
