core.sys.posix is for _POSIX_ OSes only. Much as Windows does implement some 
POSIX functions, it's is not a POSIX OS (version(Posix) blocks will not 
compile for it). If you want Windows stuff, you need to look in 
core.sys.windows, which unfortunately is currently rather sparse overall, so I 
very much doubt that there's any kind of signal handling in it right now. If 
you want additional Win32 functions, take at look at this 3rd party project:
