"Context" diff - what is it? and Perl works on 286

[UseNet Id.]

Refering to the documentation for patch (L.Wall) that performs better
with "context diff's", my xenix 2.2 (286) documentation does not show
how to get this type of diff file.  Am I still using some vanila diff
program that comes with xenix instead of a much improved GNU or L.Wall
program of similar name and function?

PS. The new 3.0 version of Perl (L.Wall) can be compiled on a 286 box
running a Xenix 2.2 that has yaccL & makeL.  Only one test fails, an
insignificant return value of status of close of a file, op.stat #42.
Compiled with flags -M2el -LARGE -O; linked with  -F 2000 -lx
malloc.c will not compile with -Zi, others will.
