Description Jukka A. Ukkonen 2002-08-11 12:50:02 UTC 
	It seemed like a good idea to allow FreeBSD to recognize
	ms-windows binaries on the fly and start wine as an interpreter
	for such binaries, if it is installed on the system.
	All it takes is adding one more very simple imgact function
	exec_wine_imgact() to the kernel.
	This is very much in analogy to how the kernel handles
	"#!" at the beginning of scripts.
	The actual benefit is lowering very much the threshold for
	windows users to start using FreeBSD instead.

Fix: The following shar bundle contains my initial version of
	exec_wine_imgact() and an include file describing the header
	parts of a windows binary. To make it obvious that this is
	just an extension I put the header to <compat/windos.h>.
	You are welcome to choose otherwise.

	Due to my systems have always had a tendency to quickly
	become somewhat modified I have no idea how well this will
	fit in any vanilla FreeBSD system, but the need for changes
	should be relatively minor. And in any case, it is the idea
	that counts.
How-To-Repeat: 
	No bug or problem, just an extension.

	Attached is a better version of the same theme. My original
	version used a compiled in constant name for the emulator.
	This of course is not appropriate, because some systems might
	prefer to use other windows support software than wine.
	The new version makes the name of the used emulator program
	a sysctl adjustable kernel MIB variable (kern.w32emu).
	The new version also fixes some other minor inconveniences
	which were present in the initial version.

	This extension requires the HW architecture being defined as
	a preprocessor macro (i386, etc) while compiling the kernel.
	It tries to check whether the binary could be run on this HW
	platform.

Over to emulation to decide its fate.

Given that no-one has looked at this bug in over 14 years I would like to close this bug as "overcome by events".  Any objections?

Would binmissctl(8) help? It's already used by poudriere + qemu-user-static to run build tools as a kind of slow cross-compilation.

  $ ./foo.exe

Added description based on comment 5 to:
 - https://wiki.freebsd.org/i386-Wine
 - https://wiki.freebsd.org/Wine

The functionality as originally intended can be achieved through the binmiscctl(8) utility.  

@gerald: any benefit of providing this functionality in a port that then runs during launch (i.e. rc.d)?

@jbeich: thank you for the explaining binmiscctl(8), I've used it before with Poudriere to create arm packages, but never realized it was more generic than that.  :-D
