[PATCH] finishing spawn / vfork signal inheritance

[Joe Buehler]

Christopher,

I see that you applied my previous patch for spawnve().  Here is
the missing part -- the parent has to copy its signal handlers to
the child.

Please check this -- this part of Cygwin is complex.  I compiled
it and it fixes vfork() and spawnve().
