I see that gettext still uses the obsolete $(mkdir_p) variable, instead of the modern equivalent $(MKDIR_P). Future Automake versions will only define the $(mkdir_p) variable when they see that the obsolete macro AM_PROG_MKDIR_P is in use as well. Since Gettext has stopped using that macro since version 0.18.2, the $(mkdir_p) variable (as well as the @mkdir_p@ substitution) will no longer be available in the makefiles and makefile recipes generated by Gettext. So it would be safer, in view of forward-comaptibility, if Gettext would start using $(MKDIR_P) exclusively, dropping any use of $(mkdir_p) that is still present.
