--- Comment #17 from Dan Kegel dank@kegel.com 2007-10-22 05:40:05 --- The bug is still present when running mdac 2.8 installer on vanilla wine from git with no settings; dasetup.log still complains about missing syssetup.dll.
I looked around for other reasons to implement syssetup.dll, and was surprised to see that some people use it to change font size: http://www.codeguru.com/cpp/misc/misc/fonts/article.php/c3757/ http://discuss.develop.com/archives/wa.exe?A2=ind0309a&L=advanced-dotnet...
Also, tape drive installer .inf files use it (not that we care): http://www.infdump.com/inffiles/T/TAPE.INF
FWIW, here's a list of exported functions: http://www.webtropy.com/articles/dll-api.aspx?dll=syssetup
