After I studied the PE / COFF - Format and looked into the OBJ-Code I've found a table for the relocation entries:
0x160:14 00 19 00 00 00 09 00 00 00 06 00 1E 00 00 00 ................
0x170:0F 00 00 00 14 00 2D 00 00 00 09 00 00 00 06 00 ......-.........
@ 0x16C is the entry for _printf. 0x1E is the address of the address part of the call instruction. The linker inserts the relocated symbol at this position. It's a 32 Bit Word. At 0x174 you find the type of the relocation. The type id is 14 and says the linker should replace this part with the relative address of printf:
IMAGE_REL_I386_REL32 0x0014 The 32-bit relative displacement of the target. This supports the x86 relative branch and call instructions.
