* libc/machine/v850/setjmp.S (_setjmp): Save r1 rather than r0.
Added return value 0.
(_longjmp): Allow longjmp to return value of second argument
passed to it.
* kill.cc (main): Change behavior of -f so that it will force the killing of a
cygwin process after waiting 2 tenths of a second for it to terminate.
(forcekill): Add an extra argument determining whether to wait for the process
to exit.
New section "Recent history of the project: What version *is* this, anyway?".

disclaimer about being out of date.
* cygheap.cc (init_cheap): Just use any old address for the cygwin heap.

exit in this thread really quickly.

incorrectly.
