manywarnings: update C warnings for GCC 13
Adjust for C programs compiled by GCC 13.
(A C++ expert still needs to look at manywarnings-c++.m4.)
* build-aux/gcc-warning.spec: Add warnings introduced in GCC 13.
* doc/manywarnings.texi (manywarnings): Document flex arrays.
* m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add
-fstrict-flex-arrays and -Wstrict-flex-arrays as these should be
suitable for Gnulib-using code.
