Bug #779 Can't change size of indexfile, error: 22

Description:
Running MySQL Distrib 3.23.54, on i32 using Win2000 NTFS. This is
where I see the error:

E:\mysql\data\test>myisamchk -O key_buffer=512M -O sort_buffer=512M -O
read_buffer=64M -O write_buffer=64M -r -S -a rsecpossqs
- recovering (with keycache) MyISAM-table 'rsecpossqs.MYI'
Data records: 54822847
myisamchk: warning: Can't change size of indexfile, error: 22
myisamchk: error: 22 for record at pos 4294967232
MyISAM-table 'rsecpossqs' is not fixed because of errors
Try fixing it by using the --safe-recover (-o) or the --force (-f) option

And this is about 4 hours after starting the command; right after myisamchk
runs through counting up the rows.

The table is the standard size, no adjustments have been made to the
AVG_ROW_LENGTH and MAX_ROWS yet. File sizes are:

4,294,967,268 rsecpossqs.MYD
4,383,221,760 rsecpossqs.MYI

at the moment. Should be cut in half after the optimize because of deletes.
Will be looking at merge tables later, but I need this working in the
mean-time.

I did some cursory looks through the source code, I've found the following:

my_chsize is being called from the mi_repair function.

Prototype for my_chsize is:

int my_chsize(File fd, my_off_t newlength, myf MyFlags);

my_off_t is a cast of unsigned __int64

inside my_chsize the function chsize is called with a prototype of:

int chsize(int, long);

basicly converting the __int64 into a long.

I'm guessing that the chsize function is a standard c function?

How to repeat:
Create a table with an index ~> 4GB on Windows.

Suggested fix:
The problem is the chsize function which only supports long integer for file
size.  I changed the config-win.h line 232 #define HAVE_CHSIZE to #undef
HAVE_CHSIZE so that the code no longer uses the chsize function.  The other
code which is implemented instead seems to correctly use __int64
all the way through, as far as I can tell (being a neophyte C programmer).

When I made the change and recompiled the myisamchk program, the execution
seems to complete successfully (although I do not know if it breaks
something else).

This is a duplicate of BUG#778.
