In section 6.2.2.1, it says:
"Declarations, like most language directives, can appear anywhere in the
file - even within other statements. "

However, there is an exception to this: you cannot put a declaration, or any
other language directive, in the middle of an array initialization.  For
example, the following is not allowed:

#declare SplineData = array[6]
{ <.6,1,-.1>,        <.54,1,-.6>,    <.5,.35,-.9>,  <.6,.35,-1.25>,
   <.6,.35,-1.65>, #declare a = 0.7;  <.3, a, -.73> }

Later in that section, it says:
"However if you attempt to re-declare an identifier as anything other than
its original type, it will generate a warning message."

This is no longer true.

In section 6.2.2.4, the line "See also "The #ifdef and #ifndef Directives""
is not a hyperlink.

 If I understood ABX' posts, he also has problems with this line. A 
simple solution would be:

"Declarations, like most language directives, can appear almost 
anywhere in the file - even within other statements. "

 This is not a solution out of laziness, but I hasitate to include one 
or two examples of exceptions. If sombody can put together a list of 
*all* exceptions, or can come up with some general text that clearly 
defines in what sort of situations exceptions may happen, I'll include 
it.



other points will be fixed.

without writing exceptions IMO this setence could be more accurate
