+  * src/rtl/hbproces.c
+    ! in process creating functions like hb_processRun(), *Open(),
+      on Android: don't use setuid( getuid() ) method for resetting
+      attributes as it rises "Bad system call" and the process is not
+      executed. This fixes building Harbour in hbmk2 stage on Android
+      device itself (for example using Termux) and can fix deploying
+      multi-process Android apps. For devices older than Android 8,
+      where the kernel was not hardened, please report any regresions,
+      if you have such multi-process deployments.
