------- Additional Comments From ehrhardt at mathematik dot uni-ulm dot de 2003-08-27 09:54 -------
Decomposing a file into preprocessing tokens is translations phase 3.
Preprocessing directives are executed in translation phase 4. This
means that even if text is skipped via #if 0 it must be a sequence of
preprocessing tokens.
In your example the double quote can not start a string constant
because a string constant must not contain a newline character (6.4.5[1]).
Note: This was accepted by older versions of gcc as an extension.
Hence the dobule quote character must be a preprocessing token of its own.
This invokes undefined behaviour (6.4[3]).
