| * Before you start changing something in this file be aware of the following: |
| * |
| * - There are several functions called recursively. In a very subtle and |
| * obscure way. DLLs can reference each other recursively etc. |
| * - If you want to enhance, speed up or clean up something in here, think |
| * twice WHY it is implemented in that strange way. There is usually a reason. |
| * Though sometimes it might just be lazyness ;) |
| * - In PE_MapImage, right before PE_fixup_imports() all external and internal |
| * state MUST be correct since this function can be called with the SAME image |
| * AGAIN. (Thats recursion for you.) That means MODREF.module and |
| * NE_MODULE.module32. |
