to the list below it.
List of executable extensions updated according to fhandler_disk_file.cc. List

Selectively using -fomit-frame-pointer when -O is used doesn't make sense
anymore, apparently since gcc 4.6, -O implies -fomit-frame-pointer.
exceptions.cc must be compiled with -fno-omit-frame-pointer on x86, as it uses
RtlCaptureContext, which requires a frame pointer.
* Makefile.in : Remove setting -fomit-frame-pointer for compiling
various files, it is already the default. Set
-fno-omit-frame-pointer for exceptions.cc on x86.

On x86_64, RtlCaptureContext() uses fxsave to save FPU/MMX/SSE state.
fxsave requires that the destination address is 16-byte aligned, or it will
fault.
CONTEXT is already annotated __attribute__ ((aligned (16))), do the same with
struct _mcontext.
Rearrange ucontext_t so that it's struct _mcontext element is also correctly
aligned.
* include/cygwin/signal.h (struct __mcontext): 16-byte align.
