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.
