- 3. in the GNU gettext tools.
- The function names in each situation must be different, to allow for
- binary incompatible changes in 'struct expression'. Furthermore,
- 1. in the GNU C Library library, the names have a __ prefix,
- 2.+3. in the GNU libintl library and in the GNU gettext tools, the names
- must follow ANSI C and not start with __.
- So we have to distinguish the three cases. */
