1766	Wrong evaluation of conditional preprocessor directives  with predefined macros __FILE__, __LINE__ and __INCLUDE_LEVEL__	daniel.wadehn@…	Hartmut Kaiser	"Checking whether one of the predefined macros {{{__LINE__, __FILE__ and __INCLUDE_LEVEL__}}} exists is not possible, wave always returns false when one of these macros is checked with the defined() operator or the #ifdef directive for example.

For example this code will trigger the error even though {{{__LINE__}}} is defined.
{{{
#ifndef __LINE__
#error ""no __LINE__""
#endif
}}}

I had a look at the source and think it can be fixed in cpp_macromap.hpp:
There are three overloads for macromap<>::is_defined(), but only one checks for the special case of those three predefined macros.
If the other overloads call the working one, the problem seems gone.

However, i have no experience with the wave source and just started having a look at it today, thats why i have no idea if there aren't any side-effects with this 'fix' and I'm looking for an official fix or a reply on this case.
I have attached my .patch though.
