I cannot reproduce this with gcc 3.3.6, the generated assembly looks just
fine for me:
0000000000000000 <test>:
0: 55 push %rbp
1: 48 89 e5 mov %rsp,%rbp
4: e8 00 00 00 00 callq 9 <test+0x9>
5: R_X86_64_PC32 hokus+0xfffffffffffffffc
9: 41 89 c0 mov %eax,%r8d
c: 41 b9 06 00 00 00 mov $0x6,%r9d
12: be 02 00 00 00 mov $0x2,%esi
17: ba 03 00 00 00 mov $0x3,%edx
1c: b9 04 00 00 00 mov $0x4,%ecx
21: 44 89 c7 mov %r8d,%edi
24: e8 00 00 00 00 callq 29 <test+0x29>
25: R_X86_64_PC32 pokus+0xfffffffffffffffc
29: e8 00 00 00 00 callq 2e <test+0x2e>
