| 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

| 80 | * -lc is given on the link command line and -lintl isn't, or

| 83 | linked to the executable at link time.

|

| 85 | would be unacceptable.
