Found while verifying -DPIP_HAS_THREADS=OFF / -DPIP_HAS_FILESYSTEM=OFF smoke builds (pre-existing gaps of the branch): - piinit.cpp: full implementation now requires PIP_HAS_THREADS as well (the PIInit class is declared in piinit.h only with threads; without threads PIInit is absent altogether, stub/absent branches unchanged) - PIWaitEvent: drop the PIP_HAS_THREADS guard - it is a plain pipe/select/WaitForMultipleObjects wrapper with no thread usage (master had no guard), restores unistd.h include for PICAN etc. - PIEthernet: guard server_thread_ member, server_func(), threaded listen/stop parts and writeThreaded() calls by PIP_HAS_THREADS - PIPeer: guard class/impl by PIP_HAS_THREADS (uses PIThread/PITimer/ PIDiagnostics), openDevice() /etc/pip.conf read by PIP_HAS_FILESYSTEM - PIBinaryLog::restart(): guard threaded-read restart by PIP_HAS_THREADS - PIIODevice::configure(config_file,...), PIConnection::configureFromConfig, PIConfig include resolution: guard path-based bodies by PIP_HAS_FILESYSTEM - PISerial::availableDevicesInfo(): guard /dev and /proc/tty scan by PIP_HAS_FILESYSTEM - PIHIDevice impl: requires filesystem (sysfs scan) in addition to threads - PIPluginLoader::pluginsDirectories/findLibrary: guard PIFile/PIDir use by PIP_HAS_FILESYSTEM (fallback: empty list / path as-is)
