Strictly speaking only -std=gnu99 support the usage of typeof and for easier inclusion in external projects, it is better to use __typeof__. CC libvhost-user.o libvhost-user.c: In function ‘vu_log_queue_fill’: libvhost-user.c:86:13: error: implicit declaration of function ‘typeof’ [-Werror=implicit-function-declaration] 86 | typeof(x) _min1 = (x); \ | ^~~~~~ Changing these two users of typeof makes the compiler happy and no extra flags or pragmas need to be provided.
