I'm trying to build Mango on Windows.  Yesterday I used SVN to get the
latest source.  When I run 'build @mango' I get compile errors in mango.io:

Can anyone suggest a solution?  I'm using DMD 0.145 </NewDUser>

This is a bizarre one.

JJR noticed the same issue on linux recently and I took a look at it yesterday. Here's where the error occurs:

class NewlineWriter : INewlineWriter
{
        private char[]  fmt;

        this ()
        {
                version (Posix)
                         this (cast(char[]) FileConst.NewlineString);
                else
                   this (FileConst.NewlineString);   // ******* ERROR HERE!
        }

        this (char[] fmt)
        {
                this.fmt = fmt;
        }
}


and here's the FileConst reference:

struct FileConst
{
        version (Win32)
        {
                static const char PathSeparatorChar = '\\';
                static const char FileSeparatorChar = '.';
                static const char RootSeparatorChar = ':';

                static const char[] PathSeparatorString = "\\";
                static const char[] FileSeparatorString = ".";
                static const char[] RootSeparatorString = ":";

                static const char[] NewlineString = "\r\n";
        }

        version (Posix)
        {
                static const char PathSeparatorChar = '/';
                static const char FileSeparatorChar = '.';
                static const char RootSeparatorChar = ':';

                static const char[] PathSeparatorString = "/";
                static const char[] FileSeparatorString = ".";
                static const char[] RootSeparatorString = ":";

                static const char[] NewlineString = "\n";
        }
}

As you can see, I hacked the Posix version to "recast" FileConst.Newline into a char[], even though it's clearly declared as one to begin with. The 'recast' gets rid of the error, but I've absolutely no idea why it happens. Perhaps Walter could shed some light on this?

To get around it for now, do the stupid 'recast' for the Win32 version also. It's really odd that this just started happening, with no changes to the related code, and only in this one very specific instance (other references to FileConst are just fine!)

Can you do shrink on it into one file?
