Hi,
most of the parts have been approved (but the i386-darwin-* files IIRC).
For completeness I submit the whole work.
Tristan.

+ @item set debug mach-o @var{num}
+ @kindex set debug mach-o
+ When set to a non zero value, enables debugging messages while gdb is
+ reading Darwin object files. (@dfn{Mach-O} is the file format used on
+ Darwin for object and executable files.) Higher values produce more
+ verbose output. This is a command to diagnose problems internal to
+ @value{GDBN} and should not be needed in normal usage.

+
+ @item set mach-exceptions on
+ @itemx set mach-exceptions off
+ @kindex set mach-exceptions
+ On Darwin, faults are first reported as a Mach exception and are then
+ mapped to a Posix signal. Use this command to turn on trapping of
+ Mach exceptions in the inferior. This might be seldom useful to
+ better understand the cause of a fault. The default is off.
