   I am not able to reproduce this problem. Can you provide more details, such as: how exactly are you building? What is the exact compiler error output you are seeing?

   reproduce command as following:

   clang -D__KERNEL_ARM_ARCH__=7 -arch armv7 -isysroot /Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk -Wall -Wundef -Werror -c -o fishhook.o fishhook.c
