PR testsuite/25241 last manual fixes

["Manuel López-Ibáñez" <lopezibanez at gmail dot com>]

This is (hopefully) the last patch that manually fixes testcases in
order to close PR 25241 for the C front-end. The next patch will
include the automatic fixes and will enable the testsuite framework to
distinguish between errors and warnings.

The least obvious of the testcases is gcc.dg/redecl-1.c. Many things
were wrong there and it is confusing to tell which line of code
produced the error (and why), and thus, whether the directive was
wrong (dg-error instead of dg-warning or viceversa) or it is the
output.

and not an error.
