* fhandler.h (set_console_state_for_spawn): Add an argument to the declaration.

* fhandler_console.cc (set_console_state_for_spawn): Ditto for the definition.
Only set invisible console for non-cygwin process.  Remove debugging leftover.
* spawn.cc (spawn_guts): Pass argument denoting whether this is a cygwin
process to set_console_state_for_spawn and only call this function when
exec'ing.
