Log Message:
ucontext.h: Expose __UCONTEXT_SIZE to userland.
But don't expose __CTASSERT(__UCONTEXT_SIZE == sizeof(ucontext_t)) to
userland.
- __UCONTEXT_SIZE will be needed soon by libc and signal trampolines
in order to version ucontext so we can safely expand it with
architecture extensions.
- __CTASSERT is not safe to use in header files in arbitrary
compilation environments (although in the NetBSD kernel build it is
safe). Exposing the __CTASSERT in a header file used by userland
appears to have the side effect of breaking the Firefox build in
rustc, though the mechanism isn't entirely clear.
Firefox/rustc discussion here:
https://mail-index.netbsd.org/pkgsrc-users/2024/05/18/msg039578.html
Let's see if this makes a difference -- if it works, great; if not,
maybe it will help us to narrow down what's happening with rustc and
Firefox.
