Check in a custom-built import library for user32 exports up to Windows XP SP2/SP3, which is used by chrome.dll in preference to the Platform SDK's user32.lib import library.

Custom build an import library for Chrome's post-WinXP imports, that binds to a fictional "user32-delay.dll".
Implement and test a delay load hook that diverts dynamic loading of any dll "foo-delay.dll" to "foo.dll".
