| 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. |

| C++, in order not to interfere with the name mangling of class fields or |
