Compiling PGP 2.6.2

For US MIT Distribution on Linux ELF systems:

You need to make two changes:

In 80386.S, change

#ifndef SYSV

to

#if !defined(SYSV) && !defined(__ELF__)

In zmatch.S, change

#ifdef SYSV

to

#if defined(SYSV) || defined(__ELF__)

In both cases, the line to change is near the top of the file.

Make these changes, and the source files will compile without a hitch.
