During 'make', with GNU make 4.3, I see these warnings:
Makefile:1027: warning: ignoring prerequisites on suffix rule definition
Makefile:1023: warning: ignoring prerequisites on suffix rule definition
Makefile:1027: warning: ignoring prerequisites on suffix rule definition
Makefile:1023: warning: ignoring prerequisites on suffix rule definition
Makefile:402: warning: ignoring prerequisites on suffix rule definition
Makefile:233: warning: ignoring prerequisites on suffix rule definition
Thanks, I fixed these; some of them just required a newer gettext.
