31 | // On AIX, and perhaps other systems, library initialization order is | |
32 | // not guaranteed. For example, the static initializers for the main | |
33 | // program might run before the static initializers for this library. | |
34 | // That means that we cannot rely on static initialization in the | |
35 | // library; there is no guarantee that things will get initialized in | |
36 | // time. This file contains definitions of all global variables that | |
