It doesn't necessarily mean that. 

Mac Gdb/Mi behaves still in most cases like FSF Gdb/Mi, there are only a handful
exceptions that usually need only some minor tweaks like adding a second code
path in the interpretation of the result. 

A bit more annoying is the different set of output data on different platforms
as this means some shortcuts when retrieving  "a full set of data" that can
be taken on one platform does not necessarily work on the other, leading
to either using the lowest common denominator or having even larger separate
code paths.
