There's no "compress" in FC, so diffstat fails for (the rare and old) *.Z patches. gzip should handle them just fine, patch attached. One example to test with: http://server.ccl.net/cca/software/LINUX/mopac7/old-version-95.06.21/mopac7-linux.diff.Z Also, upstream version 1.39 is out.
Created attachment 117590 [details] Use gzip for *.Z
Patch applied in 1.38-4. Thanks.
