System: perl version 1.0
Patch #: 26
Priority: As high as patches 24 and 25
Subject: patch 24 made use of a possibly unknown type
Description:
Some of the code for file tests calls the getgroups() system call
on systems that support it. Unfortunately, it is rather difficult
to determine what type of array it returns. On 4.3 it returns gid_t,
on our Suns, int, and on Masscomp, ushort. There is now a Configure
unit that figures it all out.
Fix: From rn, say "| patch -p0 -N -d DIR", where DIR is your perl source
directory. Outside of rn, say "cd DIR; patch -p0 -N <thisarticle".
If you don't have the patch program, apply the following by hand,
or get patch (version 2.0, latest patchlevel).
After patching:
Configure
make depend
make
make test
make install
cd x2p
make depend
make
make install
If patch indicates that patchlevel is the wrong version, you may need
to apply one or more previous patches, or the patch may already
have been applied. See the patchlevel.h file to find out what has or
has not been applied. In any event, don't continue with the patch.
If you are missing previous patches they can be obtained from me:

If you send a mail message of the following form it will greatly speed
processing:
Subject: Command
@SH mailpatch PATH perl 1.0 LIST
^ note the c
where PATH is a return path FROM ME TO YOU in Internet notation, and
LIST is the number of one or more patches you need, separated by spaces,
commas, and/or hyphens. Saying 35- says everything from 35 to the end.
You can also get the patches via anonymous FTP from
jpl-devvax.jpl.nasa.gov (128.149.8.43).
