It seems worthwhile to warn users about that since elsewhere pragmas are cross-referenced with related or equivalent attributes. gcc/ChangeLog PR c/114957 PR c/78008 PR c++/60972 * doc/extend.texi (Structure-Layout Pragmas): Add @cindex entries and reformat the pragma descriptions to match the markup used for other pragmas. Document what #pragma pack(0) does. Add cross-references to similar attributes.
