| 13 | * identical condition, but there is no corresponding `pop` pragma. This can |
| 14 | * cause trouble for code following headers above including libc headers because |
| 15 | * linker suddenly considers declarations from them (e.g., `strcmp()`) to be |
| 16 | * hidden. |
| 17 | * |
| 18 | * In order to address this situation all UDK2017 headers used by this tool |
| 19 | * must be listed above and included indirectly through this header which |
| 20 | * restores default visibility. |

| 22 | * Mind that this issue appears only if the following conditions are satisfied |
| 23 | * and not all toolchains are configured to build position-independent code by |
| 24 | * default (as if -fpic or -fpie appears on compilation command-line). |
