| 67 | library (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer). |
| 68 | If we used the unprefixed names, there would be cases where the |
| 69 | definition in the C library would override the one in the libintl.so |
| 70 | shared library. Recall that on ELF systems, the symbols are looked |
| 71 | up in the following order: |
| 72 | 1. in the executable, |
| 73 | 2. in the shared libraries specified on the link command line, in order, |
| 74 | 3. in the dependencies of the shared libraries specified on the link |
| 75 | command line, |
| 76 | 4. in the dlopen()ed shared libraries, in the order in which they were |
| 77 | dlopen()ed. |
| 78 | The definition in the C library would override the one in libintl.so if |
| 79 | either |
| 80 | * -lc is given on the link command line and -lintl isn't, or |
| 81 | * -lc is given on the link command line before -lintl, or |
| 82 | * libintl.so is a dependency of a dlopen()ed shared library but not |
| 83 | linked to the executable at link time. |
| 84 | Since Solaris gettext() behaves differently than GNU gettext(), this |
| 85 | would be unacceptable. |
| 86 | |
| 87 | The redirection happens by default through macros in C, so that &gettext |
| 88 | is independent of the compilation unit, but through inline functions in |
| 89 | C++, in order not to interfere with the name mangling of class fields or |
