I performed some tests on a workstation with WinXP at work and on my home
computer. Here are the results.

Test cases:
1) WinXP. For reference.
2) Wine 1.1.30 with five patches applied (see comment #16).
3) Wine 1.1.30 from git (downloaded about 1.5 hours ago) + patch from comment
#19.

$ grep HAVE_SCHED_SETAFFINITY include/config.h
#define HAVE_SCHED_SETAFFINITY 1
This command was executed just after Wine (test case #3) installed with
./tools/wineinstall

Screenshots of 'Test APIC' window of SIV in 3 test cases attached:
1) Reference.
2) Failed.
3) Failed.

'Processors' output of SIV:
