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. I 
don't understand how that can be right.

For a non-exception signal, we won't have aCONTEXT to provide.  Is one that is 
all zeroes acceptable?

Jon TURNEY (3):
  Rename struct ucontext to struct __mcontext
  Make mcontext and stack information available to signal handlers
  Add cygwin_internal() operation to convert siginfo_t * to
    EXCEPTION_RECORD *
