WString-plus-int

The following is really a bug in the code. But I am unable to understand how array indexing can silence this.

An explanation would help.

note: use array indexing to silence this warning
"ProtocolIFType == " + _pift );
^
& [ ]

The suggestion is to rewrite it as '&"ProtocolIFType == "[_pift]'
(i.e. taking the address of a character in the string). Granted, the
compiler's output isn't as clear as it could be.
