Wine runs on OpenBSD after a workaround for the %gs segment register

marc.info Editor score 7/10

The OpenBSD port emulates %gs-prefixed commands because the system cannot set gsbase, and testers report success with dozens of 64-bit Windows applications. It is a concrete example of the compatibility work needed to bring a large software stack to another OS.

What

A proposed OpenBSD port of Wine runs 64-bit Windows software on the operating system.

How

Because OpenBSD cannot set gsbase, the port emulates the %gs prefix on commands; testers report success with dozens of 64-bit programs.

Why it matters

The workaround enables software compatibility across different OS and CPU environments, though WoW64 and 32-bit Windows apps remain unsupported.
