I've got a few minor problems with the specifications for the
preprocessor.

The issue of incomplete /* comments in preprocessor commands is one.

#define fred a + /* incomplete
comment spans lines here */ b

Is the above legal?

The ARM claims

"The source text is decomposed into preprocessing tokens and sequences
of white space. A single white space replaces each comment. A source
file may not end in a partial comment.

[Then, on the next pass]

"Preprocessing directives are executed and macros expanded".

This is a bit tricky. For a start this seems to imply
preprocessor commands can be continued by comments, since
the comments are just replaced by white.

But then it is absurd because if all the newlines were replaced
by white (they are white anyhow) then there would be no way
to delimit the end of the preprocessor command.

Secondly, there might be problems with

#include <filename>

since the < and > are toke. But the filename is implementation dependent.
To fix this, one would have to parse the '#include' tokenising
the rest of the line. (contrary to the ARM requirement).

Any help?
