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.
