What you can do :

1) to analyze the error more deeply, try to create a gzipped file with ant
and gunzip it with ant on your platform. 
2) compare the binary look and feel of the gzip created by ant and the other
gzip file which is failing to be gunzipped
3) if you do not find an explanation in steps 1) and 2)
file a bug report with a sample build file and a sample gz file which fails
to be gunzipped by ant (as attachment of course).
indicate in the bug report how the gzip file which ant fails to expand is
being created (which utility, on which platform)

Cheers,

Antoine
