setjmp/longjmp are available on windows (image loaders using 
libpng, lua, quake3, and lots of old C code make use of them):

You can declare the functions in your own code and they should 
link just fine. It would be helpful if you also submit a PR to 
add them to DRuntime for Windows.

As for sigaction, a quick search suggests it isn't available (and 
it doesn't show up in MSDN):
