Remove support for HP-UX

petk · petk · commit 8adb7dbe827b · 2026-02-24T12:42:09.000+01:00
HP-UX is discontinued system since 2026-01-01: https://userapps.support.sap.com/sap/support/knowledge/en/3629028 Recent compilers also don't work there anymore. Changes: - Non-standard '-threads' flag check removed. - ZEND_HRTIME_PLATFORM_HPUX preprocessor macro renamed to ZEND_HRTIME_PLATFORM_SUNOS as it is now related to only Solaris/illumos systems. - Check for HP-UX style reentrant time functions adjusted. This wasn't reproducible on any known system so far. - LOG_NEWS and LOG_UUCP conditions removed as all Unix-like systems should have them (Windows build have definitions provided in win32/syslog.h). - Check for <sys/pstat.h> header removed as it is relevant only on HP-UX. - The '.sl' file extension for shared PHP extensions is with this also removed, making extension either .so (Unix-like systems), or .dll (Windows).
