Warnings while building 3.01 using VS2008?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build tesseract 3.01 using my newly proposed VS2008 files.

What is the expected output? What do you see instead?
No warnings.
Even after I turn off the following warnings (as discussed in 
http://groups.google.com/group/tesseract-dev/msg/da4ab9b046876d7e):

   /wd4005: 'snprintf' : macro redefinition

   /wd4018 'expression' : signed/unsigned mismatch

   /wd4244 conversion from 'double' to 'float', possible loss of data

   /wd4355: 'this' : used in base member initializer list

   /wd4267 conversion from 'size_t' to 'type', possible loss of data

   /wd4305 truncation from 'type1' to 'type2'

   /wd4800: forcing value to bool 'true' or 'false' (performance
warning)

   /wd4996 'function': was declared deprecated 

I still see these remaining 8 warnings:

   warning C4804: '>' : unsafe use of type 'bool' in operation  ccstruct\werd.cpp   473
   warning C4566: character represented by universal-character-name '\u2000' cannot be represented in the current code page (1252)  dict\trie.cpp   43
   warning C4566: character represented by universal-character-name '\u2001' cannot be represented in the current code page (1252)  dict\trie.cpp   44
   warning C4566: character represented by universal-character-name '\u2002' cannot be represented in the current code page (1252)  dict\trie.cpp   45
   warning C4566: character represented by universal-character-name '\u2003' cannot be represented in the current code page (1252)  dict\trie.cpp   46
   warning C4566: character represented by universal-character-name '\u2004' cannot be represented in the current code page (1252)  dict\trie.cpp   47
   warning C4566: character represented by universal-character-name '\u2005' cannot be represented in the current code page (1252)  dict\trie.cpp   48
   warning LNK4221: no public symbols found; archive member will be inaccessible    quadratc.obj

What version of the product are you using? On what operating system?
My new solution mentioned in "Enhancing the tesseract 3.01 Visual Studio 2008 
distribution" 
(http://groups.google.com/group/tesseract-dev/msg/da4ab9b046876d7e).
Visual Studio 2008
Windows 7 SP1

Please provide any additional information below.
I have no idea what the middle 6 are, but the first warning looks like a real 
error to me;

      if ((not_found_box.major_overlap(a_blob_box) ||
           a_blob_box.major_overlap(not_found_box)) &&
           not_found_box.y_overlap(a_blob_box) > 0.8) {

where y_overlap is defined in rect.h as:

   inline bool TBOX::y_overlap(const TBOX &box) const {
     return ((box.bot_left.y() <= top_right.y()) &&
       (box.top_right.y() >= bot_left.y()));
   }

So it seems like the check is to see if a bool > 0.8???

Not sure what is going on with the last warning either. In the past, I've seen 
that when everything in a file is somehow #ifdef'ed out. quadratc.cpp just 
includes quadratc.h, but that file defines a class and also includes points.h 
which defines a bunch of things?

closing this issue, because in svn there is new solution build from scratch. 
Please feel free to improve it.

My new solution fixes (by turning off) most of the warnings but a real bug is 
still in ccstruct\werd.cpp [1]. Should I submit that bug as a separate issue. 
It apparently got lost in all the other stuff.
