Is there a reason this option doesn't extend to the C frontend?  The same
problem with useless static_casts occurs with conventional C casts, too.

[Bug c/84510] New: C front-end does not utilise -Wuseless-cast

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84510

Bug ID: 84510
   Summary: C front-end does not utilise -Wuseless-cast
   Product: gcc
   Version: 5.4.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c
  Assignee: unassigned at gcc dot gnu.org
  Reporter: bje at gcc dot gnu.org
  Target Milestone: ---

The -Wuseless-cast option only applies to C++ and Objective C. It would also be
useful in the C front-end, particularly for finding 'do nothing' casts and
casts of literals, which the compiler can do itself by inferring the type of
the literal.

Fixed with:

 PR testsuite/70719
* testsuite/lib/libjava.exp (libjava_arguments): Use 'file
normalize' rather than the defunct DejaGnu 'absolute' proc.
