It isn't. Please rename cr2 to ctx_flags and add a

Patch is ok, except for the __COPY_CONTEXT_SIZE part. This requires
a change to st
The gethostname function has a problem where a small buffer size will
not produce an accurate errno. This is because the Windows error is
not being appropriately mapped. This causes programs such as hostname
from coreutils to fail because they are not informed about the long
name.

Add ucontext.h header, defining ucontext_t and mcontext_t types.
Provide sigaction sighandlers with a ucontext_t parameter, containing stack and
context information.

Thanks for your help so far. Here's another attempt at this.
Questions:
The ContextFlags member of the CONTEXT type is named cr2 in struct __mcontext.

don't understand how that can be right.
For a non-exception signal, we won't have aCONTEXT to provide. Is one that is
