"bool.h" is not part of C++ standard, rather part of libg++, which is 
deprecated; perhaps your mingw32 gcc distribution does not include 
it? Note that it's non-standard header, and any code that expects it is 
broken, plain and simple. 

FYI, EGCS 1.0.2 mingw32 distribution does include libg++, and hence bool.h.
See http://www.xraylith.wisc.edu/~khan/software/gnu-win32/ for more info.

BTW, I believe that Jan-Jaap has a port of V on his web page. Follow my 
link above to get to his.

Use something else! Of course, I don't see the need for using this "double 
typedef". All it does is add complexity where none is needed or desired. 
Why not just use "bool" if you're using C++ to begin with?
