Error: A00001 Unreconciled syntax error

[trouble96]

I'm trying to build "example_freertos_getting_started" but

[ 63%] Building C object CMakeFiles/tile1_example_freertos_getting_started.dir/modules/rtos/modules/FreeRTOS/FreeRTOS-SMP-Kernel/portable/ThirdParty/xClang/XCOREAI/port.c.obj

Also, trying to build under Windows 10 system (vs 2019), same error happened "A0001 Unconciled syntax error" in same file - /XCOREAI/port.c
