*
* Note that "pragma GCC diagnostic push/pop" was added in GCC 4.6, Mar 2011;
* clang only pretends to be GCC 4.2, but still supports push/pop.
*
- * Note on usage: on non-gcc (or lookalike, like clang) compilers
- * one cannot use these with a semicolon at file (global) level without
- * warnings since they are defined as empty, which leads into the terminating
- * semicolon being left alone on a line:
- * ;
- * which makes compilers mildly cranky. Therefore at file level one
- * should use the GCC_DIAG_IGNORE and GCC_DIAG_RESTORE macros *without*
- * the semicolons.
+ * Note on usage: all macros must be used at a place where a declaration
+ * or statement can occur, i.e., not in the middle of an expression.
+ * *_DIAG_IGNORE() and *_DIAG_RESTORE can be used in any such place, but
+ * must be used without a following semicolon. *_DIAG_IGNORE_DECL() and
+ * *_DIAG_RESTORE_DECL must be used with a following semicolon, and behave
+ * syntactically as declarations (like dNOOP). *_DIAG_IGNORE_STMT()
+ * and *_DIAG_RESTORE_STMT must be used with a following semicolon,
+ * and behave syntactically as statements (like NOOP).
*
- * (A dead-on-arrival solution would be to try to define the macros as
- * NOOP or dNOOP, those don't work both inside functions and outside.)
