The C Standard doesn't guarantee support for -128 and -32768. This originally was for ones' complement machines such as the Unisys ClearPath Dorado enterprise servers (still in use via firmware translation to Intel Xeon, and they have a C compiler),Are they still used in production for programs written in C?
Yes, it does appear C is still active there; Unisys has a C reference manual dated 2015 <https://public.support.unisys.com/aseries/docs/clearpath-mcp-17.0/pdf/86002268-206.pdf> and they're still selling those mainframes with new hardware released this year <https://www.app5.unisys.com/library/gmMail/emails/documents/CP-June19/poweredby_june2019.html>.
PS. They also support Cobol, Fortran, and some other languages. (The world is still waiting patiently for Bison to support Cobol. :-)
