Port Wine to amd64

Contact: port-amd64, tech-kern

IMPORTANT: This project was completed by Naveen Narayanan (GSoC 2019). You may still contact the people above for details, but please do not submit an application for this project.

The Wine program is made of two components, Wine32 and Wine64, that respectively allow 32bit or 64bit Windows binaries to run on UNIX-like systems.

Until now, Wine32 could not work on NetBSD-amd64, because the USER_LDT option was not available in the kernel.

This option was recently added, so Wine32 can now be ported to NetBSD-amd64.

Milestones:

Test a static Wine32 on amd64. That is, compile Wine32 statically on NetBSD-i386, and launch it on NetBSD-amd64 (which supports running native 32bit binaries). See if it works, and if not, apply the necessary fixes. At this stage, old Windows video games should work.
Make a dynamic Wine32 work on amd64. Compile Wine32 on NetBSD-i386 in a non-static way, and launch it on NetBSD-amd64.
Make Wine32+Wine64 work on amd64. See the WineHQ wiki on how to achieve this. At this stage, 64bit Windows binaries that use 32bit libraries should work.
Package Wine32+Wine64 for pkgsrc.
