Re: no conversion from char[] to char* on function calls under circumstances [was: A bug?]

C++98 is not C99 :) there is no rvalue to lvalue conversion for rvalue arrays in C++98. Also this code is still undefined C99 but will most likely become valid C1x. Sent from my iPhone On Dec 16, 2008, at 8:45 AM, Jan Engelhardt wrote: On Tuesday 2008-12-16 17:05, Michel Van den Bergh wr

Re: C/C++ FEs: Do we really need three char_type_nodes?

Yes char, unsigned char and signed char are three distant types. Unlike the other interger types in C/C++. That is they are incompatable types. Thanks, Andrew Pinski Sent from my iPhone On Sep 19, 2008, at 9:36 AM, "Diego Novillo" <[EMAIL PROTECTED]> wrote: When we instantiate char_typ
