The following patch attempts to document the PR36113 changes to the GNU C extension support of enumerators which don't fit into int. Ok for wwwdocs? Shall we mention it in porting_to.html as well?

  • The behavior of the GNU C extension support of enumerators which + don't fit into int has been changed to match the C2X + behavior. Previously, in enumerations where at least one enumerator + didn't fit into int, only those enumerators that didn't + fit into int had the enum type and others + had int type and while the enum is being + defined enumerators that didn't fit into int had some + unspecified type with the sign and precision of its value. + In GCC13, in such enumerations all enumerators have the + enum type and while the enum is being + defined enumerators that didn't fit into int have + type of their value. If all enumerators fit into int + type, as before all enumerators have int type, both + while the enum is being defined and after it is defined. + See PR36113 for details. +
