First let me say that you have an old version of Amanda. But I don't know where 
your problem come from.
I only thing I can say is that, in my case (amanda 2.4.3), I also have problems 
with Cygwin and index generation. Amanda does not tell me that there was a 
problem during the backup; but when I try to amrecover my cygwin files, the 
program sometimes tells me "no index records for host" and when I go and see 
the file, it tells me the gzip file for record is incorrect:
--- cut here ---
amanda@backup2:~$ amgetconf test indexdir
/BACKUP/amanda/var/test/index
amanda@backup2:~$ gzip -t 
/BACKUP/amanda/var/test/index/mdb0/_cygdrive_g_BACKUP__MDB1_Night__dump/20030606_0.gz
 

gzip: 
/BACKUP/amanda/var/test/index/mdb0/_cygdrive_g_BACKUP__MDB1_Night__dump/20030606_0.gz:
 unexpected end of file
--- cut here ---

So, in my case, I am not able to amrecover the files, but they surely went to 
tape and I can amrestore them without problem...

Try see if you don't have a similar problem to mine.
