TestBot uses a different algorithm to check if a test should be skipped.
Winetest.exe checks the name of the test and obtains the name of the DLL
being tested from that (msxml3_test.exe => msxml3.dll). If that DLL is
not present, winetest.exe skips the test. TestBot checks the import
table of the test executable, and if any of the statically imported DLLs
are missing it skips the test. In this case, msxml3.dll is not statically
linked, so it will not be skipped by TestBot on NT4. TestBot should
probably check the test name too.
