+Subject: [PATCH] test: handle POSIX ioctl prototype
+
+glibc has the following prototype for ioctl: int ioctl(int fd, unsigned long request, ...)
+POSIX (inc. musl) has the following for ioctl: int ioctl(int fd, int request, ...)
+
+Check which prototype is used in <sys/ioctl.h> to avoid a conflict and conditionally
+define the right one for the system.
