egrep with -i option ????

[Wolf PAUL]

Does anyone have a freely-distributable version of egrep which
is compatible with the egrep in SunOS 4.x ?

I.e. an egrep with the following synopsis:

egrep [ -bchilnsv ] [ -e expr ] [ -f fname ] [ expr ] [ fname... ]

On our Ultrix-3 system, egrep does not support the -i (ignore case)
option, nor does the 4.3BSD source we have here. It does not seem
trivial to me to add -i support to egrep.y.
