https://cygwin.com/ml/cygwin/2015-07/msg00344.html:
RtlFillMemory and RtlCopyMemory only work for size values
up to 2GB. Fix this problem by using NetBSD code for
memset and memcpy. Add entry points for memmove, wmemset,
wmemmove, wmemcpy. Thanks to Roman Petrovski
<RPetrovski@illumina.com> for pointing this out.
* miscfuncs.cc (memset): x86_64 only: Implement in assembler.
(memmove,memcpy): x86_64 only: Ditto.
(wmemmove,wmemcpy): x86_64 only: Ditto.

* cygtls.h: Include cygtls_padsize.h and define CYGTLS_PADSIZE there.
* cygtls_padsize.h: New file. Define CYGTLS_PADSIZE.
* environ.cc (parse_options): Fix NULL pointer access.
* init.cc (threadfunc_fe): Do not force stack align on x86_64.
* strace.cc (main2): Rename from main.
(main): Make room for _cygtls area on stack and just call main2. Add
comment to explain why.

* uinfo.cc (cygheap_user::ontherange): Ignore $HOME if it's not
starting with a slash (aka, absolute POSIX Path).

* libc/include/machine/setjmp.h (siglongjmp): Declare as function on
Cygwin.
(sigsetjmp): Ditto.
(_longjmp): Mark as noreturn function on Cygwin.
* common.din (siglongjmp): Export.
(sigsetjmp): Export.
* gendef: Change formatting of some comments.
(sigsetjmp): Implement.
(siglongjmp): Implement.
(__setjmpex): x86_64 only: Drop entry point.
(setjmp): x86_64 only: Store tls stackptr in Frame now, store MXCSR
and FPUCW registers in Spare, as MSVCRT does.
(longjmp): x86_64 only: Restore tls stackptr from Frame now, restore
MXCSR and FPUCW registers from Spare.
* include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Bump.
* new-features.xml (ov-new2.2): Document sigsetjmp, siglongjmp.
