I seriously don't think you will ever convince anyone to change a facet
of gcc which is currently following the standard to something that is
non-standard.

Besides, you can solve the unique name problem like this:

#define UNIQUIFY2(a,b) a##b
#define UNIQUIFY1(a,b) UNIQUIFY2(a,b)
#define UNIQUIFY(x) UNIQUIFY1(x_,__COUNTER__)

#define macro(a) \
({               \
   __typeof(a) UNIQUIFY(a) = (a);  \
/* ... some code ... */ \
})

__COUNTER__ was new in 4.3.
