problem with USER_LDT in current 9.99.81

[Dave Tyson <dtyson%anduin.org.uk@localhost>]

I have wine 4.4 working under NetBSD 9.99.23 amd64 (> 1 year ago) and recently 
tried against a recent current - 9.99.81.

Wine now complains:
i386_set_ldt: Operation not permitted
Did you reconfigure the kernel with "options USER_LDT"?

but GENERIC has the option enabled and strings on the kernel shows:

_CFG_options \011USER_LDT\011# User-settable LDT, used by Wine
_KERNEL_OPT_USER_LDT

I am guessing a change between 9.99.23 and 9.99.81 has broken the 
functionality, but before I bisect does anyone have any ideas...

Cheers,
Dave
