David Macek bbc87a02fd Fix inconsistencies in docs regarding fstab and executable file detection
The inline list of mount options seemed redundant, so the paragraph now points
to the list below it.

List of executable extensions updated according to fhandler_disk_file.cc. List
of executable magic numbers updated according to path.h (has_exec_chars).

	* pathnames.xml: Fix inconsistencies in docs regarding fstab and
	executable file detection

Jon TURNEY 4f28e8a0e5 Compile exceptions.cc with -fno-omit-frame-pointer on x86
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

Jon TURNEY 383ff5fc47 Try to make sure struct _mcontext is 16-byte aligned
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.
