7159,Text-lines are processed as if they were preprocessing directives,tomasz.miasko@…,Hartmut Kaiser,"Wave treats some text-lines as if they were preprocessing directives. 
This behaviour is trigger by following code, which is an example taken from C99 standard, with an additional newline:

{{{
#define EMPTY

EMPTY # include <file.h>
}}}


{{{
$ wave --c99 example.c 
example.c:3:7: error: could not find include file: file.h
}}}

Relevant part of C99 standard:
 A preprocessing directive consists of a sequence of preprocessing tokens that satisfies the following constraints: The first token in the sequence is a # preprocessing token that (at the start of translation phase 4) is either the first character in the source file (optionally after white space containing no new-line characters) or that follows white space containing at least one new-line character.

It seems the same is true for other C/C++ standards, even if they do not specify that this conditions should occur at start of translation phase 4 (http://www.open-std.org/jtc1/sc22/wg14/docs/rr/dr_144.html).",Bugs,closed,To Be Determined,wave,Boost Development Trunk,Problem,fixed,,
