I believe VC++ correctly rejects the code because it implements DR #whatever, that went into the TC1 as 3.4.3.1/1a. G++ does not implement that rule. -- Gabriel Dos Reis gdr@cs.tamu.edu Texas A&M University -- Computer Science Department 301, Bright Building -- College Station, TX 77843-3112 --- [ comp.std.c++ is moderated.
