Running MySQL Distrib 3.23.54 on i32. 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.

How to repeat:
Create a large table with indexes that will exceed the 4Gb size (32bit unsigned int).  Run myisamchk -r -S -a against the table.

Suggested fix:
Patch config-win.h:
Line 232:
-#define HAVE_CHSIZE        /* System has chsize() function */
+#undef HAVE_CHSIZE        /* System has chsize() function but is only 32 bit*/
