- If we used the unprefixed names, there would be cases where the
- definition in the C library would override the one in the libintl.so
- shared library. Recall that on ELF systems, the symbols are looked
- up in the following order:
- 1. in the executable,
- 2. in the shared libraries specified on the link command line, in order,
- 3. in the dependencies of the shared libraries specified on the link
- command line,
- 4. in the dlopen()ed shared libraries, in the order in which they were
- dlopen()ed.
- The definition in the C library would override the one in libintl.so if
- either
- * -lc is given on the link command line and -lintl isn't, or
- * -lc is given on the link command line before -lintl, or
- * libintl.so is a dependency of a dlopen()ed shared library but not
- linked to the executable at link time.
- Since Solaris gettext() behaves differently than GNU gettext(), this
- would be unacceptable.
- The redirection happens by default through macros in C, so that &gettext
- is independent of the compilation unit, but through inline functions in
- C++, in order not to interfere with the name mangling of class fields or
- class methods called 'gettext'. */
