From: Fotios Valasiadis <fvalasiad(a)gmail.com> After commit 898ab8dab19d498c17859f39a55e317ee7e367a5 wine would no longer build on musl. Issue is that apparently TCSETS2 isn't defined when including sys/ioctl.h. A little digging shows that glibc goes ahead and includes asm/ioctls.h in sys/ioctl.h, providing said macro. Musl on the other hand doesn't and relies on bits/ioctl.h, which lacks said macro. Since there is no mention in the manpage about the need to include asm/ioctls.h, uncertain if that's an issue with musl or the manpage, would like some help on that front so I can go open PRs to fix that respectively.
