Hmm, I don't immedeately see how shared sections can cause a wrong
jump into wine's code. But I will think of this.

Anyway, here is another one, looking slightly different. It is by
using native rasapi32 with Agent news reader.

| err:win32:fixup_imports No implementation for KERNEL32.dll.48879 imported from D:\win98\system\netbios.dll, setting to 0xdeadbeef
| err:win32:fixup_imports No implementation for KERNEL32.dll.48879 imported from D:\win98\system\netbios.dll, setting to 0xdeadbeef

I don't get this message with the first instance of Agent, nor with
builtin rasapi32 and IIRC also not a week ago.
