It looks like it failed to remove a *.log file under windows, which
caused rmtree to fail.

src/bin/pg_upgrade/pg_upgrade.h-#define DB_DUMP_LOG_FILE_MASK   
"pg_upgrade_dump_%u.log"
src/bin/pg_upgrade/pg_upgrade.h-#define SERVER_LOG_FILE         
"pg_upgrade_server.log"
src/bin/pg_upgrade/pg_upgrade.h-#define UTILITY_LOG_FILE        
"pg_upgrade_utility.log"
src/bin/pg_upgrade/pg_upgrade.h:#define INTERNAL_LOG_FILE       
"pg_upgrade_internal.log"

ee5353abb only changed .txt files used for errors so can't be the cause,
but the original commit 38bfae3 might be related.

I suspect that rmtree() was looping in pgunlink(), and got ENOENT, so
didn't warn about the file itself, but then failed one moment later in
rmdir.
