[Bug-ocrad] visual studio 2008 and ocrad 0.17 and ocrad 0.18 pre release

[Muhammad Umar Janjua]

I am compiling ocrad 0.17 and 0.18 pre release with
visual studio 2008 on windows xp.

There following change was needed

1) void internal_error( const char * msg ) throw();//
__attribute__ ((noreturn));


The __attribute__ ((noreturn)) was not recognizable.
So I commented it out.

The compilation was successful with warnings
ucs.cc(253) : warning C4309: 'return' : truncation of
constant value

bitmap.h(48) : warning C4800: 'const char' : forcing
value to bool 'true' or 'false' (performance warning)

page_image.h(35) : warning C4290: C++ exception
specification ignored except to indicate a function is
not __declspec(nothrow)

main.cc(348) : warning C4996: 'fopen': This function
or variable may be unsafe. Consider using fopen_s
instead.

and others ....



However, when I ran the generated program with
test.pbm, the program gave a runtime debug assertion
violation. The call stack is
