The -Wuseless-cast warning option, in particular, is a coding style option:
- It never points to dangerous code.
- As soon as one uses typedef, it is normal to cast from type T1
to type T2 even if T1 and T2 happen to already be the same.
- Also, in function-like macros, it is commonplace to use casts,
just to make sure the operations are done on specific types.
These casts also often trigger -Wuseless-cast warnings.
In a gnulib testdir, there are 446 warnings of this type (log attached).
Which shows that this warning option is not useful for Gnulib.
I'm therefore disabling it:

Silence -Wuseless-cast in all Gnulib compilation units.
* m4/gnulib-common.m4 (gl_CC_GNULIB_WARNINGS): Add -Wno-useless-cast.
