POSIX is an acronym for Portable Operating System Interface.

Although originated to refer to the original IEEE Std 1003.1-1988, the 
         ^^^^^^^^^^                                        ^

[note that Shell and Utilities is .2]

name POSIX more correctly refers to a family of related standards: IEEE 
Std 1003.n (where n is a number) and the parts of ISO/IEC 9945. The term 
POSIX was originally used as a synonym for IEEE Std 1003.1-1988. A 

preferred term for that standard, POSIX.1, emerged. This maintained the 
advantages of readability of the symbol ``POSIX'' without being ambiguous 
with the POSIX family of standards.

For a full listing of the project numbers see PASC Standing Document SD11.

The name POSIX was suggested by Richard Stallman. 

First released in 1974, MVS was later renamed by IBM, first to MVS/XA 
(eXtended Architecture), next to MVS/ESA (Enterprise Systems 
Architecture), then to OS/390 when UNIX System Services (USS) 

were added, and finally to z/OS when 64-bit support was added on the 
zSeries models. Its core remains fundamentally the same operating 
system. By design, programs written for MVS can still run on z/OS 
without modification.


    Company Name: IBM Corporation

    Product Name: z/OS V1R2 or later with: Security Server and z/OS 
    V1R2 or later C/C++ Compiler on IBM zSeries Processors that 
    support z/OS Version 1 Release 2 or later

And regarding [Guh-NÜ-slash-]Linux, POSIX.1 is basically kernel+[g]libc.
