I'm currently on Linux CentOS 7. I'm on Povray version
3.7.1-alpha.7695039.unofficial (but this also didn't work on Povray version 3.7
RC7). When I try to run Povray in terminal with STDIN I receive a "Render
failed" error.

Command I'm running:

cat pov.pov | povray +I-


Error:

Possible Parse Error: Cannot find file '-', even after trying to append file
 type extension.
Parse Error: Cannot open input file.
Fatal error in parser: Cannot parse input.
Render failed

Please let me know if you need more information.

This is not supported.

The #macro system need to move back in file(s), which is not possible
with the stdin stream. Other functionalities also move back in file(s).
(such as loop)

The right call is:
* povray -Ipov.pov

Or

* cat - >pov.pov && povray -Ipov.pov
-- 
IQ of crossposters with FU: 100 / (number of groups)
IQ of crossposters without FU: 100 / (1 + number of groups)
IQ of multiposters: 100 / ( (number of groups) * (number of groups))

http://www.povray.org/documentation/3.7.0/r3_2.html#r3_2_5_2

So is the documentation saying it's only possible on Windows? Or is the
documentation just out of date and it's not possible anywhere anymore?

I guess this was removed intentionally and the docs are out of date.
