POSIX Compliance - open-watcom/open-watcom-v2 GitHub Wiki
Many needed header files and parts of the runtime implementation for the POSIX System Interface compatibility are missing or incomplete.
POSIX requires _POSIX_VERSION to be defined in unistd.h and Open Watcom uses:
#define _POSIX_VERSION 199809L
Expect features of newer POSIX System Interface versions to be missing.
There is no exact overview, which features of the advertised POSIX version are implemented and which features are still missing.
