+dnl On ELF systems, linking a program against a string table in shared
+dnl library is very expensive and actually makes things much worse than
+dnl just duplicating the needed strings in the program.
+dnl
+dnl It may help a little bit when static linking or on other shared
+dnl library implementations, which could maybe be auto-detected with
+dnl a configure test, but the penalty for setting these anyway is
+dnl very small (couple hundred bytes of rodata).
