/* Names for the libintl functions are a problem. This source code is used
1. in the GNU C Library library,
2. in the GNU libintl library,
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. */
