wine commit id f6b3dba7a08a718f633804da508e4586ae72e6f5 by Alexandre Julliard <julliard@winehq.org>

SYNC NOTE: This is Wine-specific functionality, placed in __WINESRC__
REG_LINK is _NOT_ supported by (official) Windows INF AddReg section.
See the WDK ChkInf.pm tool (from Win2003 up to Win10), for example at:
https://github.com/skycipher/CNGProvider/blob/master/Windows%20Kits/10/Tools/x86/ChkInf/chkinf.pm#L3870
