// g++ 1.37.1 bug 900404_04// [dcl.dcl] explains that simple-declarations may omit the// init-declarator-list only if the decl-specifier-seq declares a// class, i.e. if it contains a class-specifier, an// elaborated-type-specifier with class key, or an enum-specifier. The// declaration below contains neither.// g++ fails to flag errors for such usage.// keywords: semicolon, vacuous, file scope, declarationint i;;			// ERROR - , XFAIL *-*-*int main () { return 0; }
