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 __.
