From 2f6b9896acc16aa8aa3b2308fa247760446a916c Mon Sep 17 00:00:00 2001 From: Ben Marsh Date: Thu, 20 Jun 2024 15:26:17 +0100 Subject: [PATCH] posix: sys: sysconf: Unconditionally define POSIX macros The POSIX macros PAGE_SIZE and PAGESIZE (queriable through sysconf()) were conditionally defined only if an existing definition did not already exist. These should be defined unconditionally in their header to ensure they get the correct values. If these macros are defined elsewhere with a different meaning, that's a problem. There was an issue where PAGESIZE was already defined with a different meaning. See #74623 and #74428. The POSIX macro ATEXIT_MAX is also conditionally defined and should be unconditionally defined, but there is currently a definition in picolibc (picolibc/newlib/libc/include/stdlib.h) so this change will be done separately. This commit defines PAGE_SIZE, and PAGESIZE unconditionally.
