gzip 1.3.10 zdiff on Tru64 4.0F

[Thomas Koutcher]

Hi,

On Tru64 4.0F zdiff is using ksh Version M-11/16/88f. ksh has some support for
the syntax /dev/fd/n and thus the command "test -r /dev/fd/3 3</dev/null"
returns 0 but this syntax does not work for external commands: there is no
/dev/fd linked to /proc as there is on Linux and the result when using make
check is:

./zdiff -c gzip.doc.gz gzip.doc.gz
diff: /dev/fd/3: No such file or directory
*** Exit 2
Stop.

Please find attached a correction proposition which passes make check.
