Mbed-os: Application Header - mbed compile warning

[DBS06]

Description

I added an application header to my mbed_app.json like described here Adding an application header. So far so good, but when I do this I get from the command line with mbed compile the following error:
[Warning] <command-line>@0,0: "HEADER_ADDR" redefined

I found out that the warning is a result at calling the arm-none-eabi, i.e.:
[DEBUG] Compile: arm-none-eabi-g++ -std=gnu++11 -fno-rtti -Wvla -c -Wall -Wextra -Wno-unused-parameter -Wno-missing-field-initializers -fmessage-length=0 -fno-exceptions -fno-builtin -ffunction-sections -fdata-sections -funsigned-char -MMD -fno-delete-null-pointer-checks -fomit-frame-pointer -Os -DNDEBUG -g1 -mcpu=cortex-m4 -mthumb -mfpu=fpv4-sp-d16 -mfloat-abi=softfp -DBOOTLOADER_ADDR=0x0 -DBOOTLOADER_SIZE=0xc800 -DHEADER_ADDR=0xc800 -DHEADER_SIZE=0x10 -DAPPLICATION_ADDR=0xc810 -DAPPLICATION_SIZE=0x3fff0 -DHEADER_ADDR=0x4c800 -DHEADER_SIZE=0x10 -DPOST_APPLICATION_ADDR=0x4c810 -DPOST_APPLICATION_SIZE=0xb37f0 -DDEVICE_SPI=1 -DMBED_BUILD_TIMESTAMP=1528795199.65 -D__MBED__=1 -DTARGET_1024K -D__FPU_PRESENT=1 -DDEVICE_PORTINOUT=1 -DTARGET_RTOS_M4_M7 -DTARGET_EFM32PG12 -DDEVICE_LOWPOWERTIMER=1 -DDEVICE_RTC=1 -DTOOLCHAIN_object -DDEVICE_SERIAL_ASYNCH=1 -D__CMSIS_RTOS -DTRANSACTION_QUEUE_SIZE_SPI=4 -DMBEDTLS_CONFIG_HW_SUPPORT -DTOOLCHAIN_GCC -DDEVICE_SPISLAVE=1 -DARM_MATH_CM4 -DDEVICE_I2C_ASYNCH=1 -DTARGET_LIKE_CORTEX_M4 -DTARGET_M4 -DTARGET_UVISOR_UNSUPPORTED -DDEVICE_SPI_ASYNCH=1 -DDEVICE_SERIAL=1 -DMBED_TICKLESS -DDEVICE_INTERRUPTIN=1 -DTARGET_CORTEX -DDEVICE_I2C=1 -DDEVICE_PORTOUT=1 -DDEVICE_I2CSLAVE=1 -D__CORTEX_M4 -DDEVICE_STDIO_MESSAGES=1 -DTARGET_LIKE_MBED -DEFM32PG12B500F1024GL125 -DDEVICE_PORTIN=1 -DTARGET_RELEASE -DTARGET_EFM32 -DDEVICE_TRNG=1 -D__MBED_CMSIS_RTOS_CM -DDEVICE_SLEEP=1 -DTOOLCHAIN_GCC_ARM -DTARGET_EFM32PG12_STK3402 -DTARGET_Silicon_Labs -DTARGET_SL_CRYPTO -DDEVICE_ANALOGIN=1 -DDEVICE_PWMOUT=1 -DTARGET_EFM32PG12B500F1024GL125 -DDEVICE_FLASH=1 -DTARGET_CORTEX_M @BUILD_RELEASE\bootloader-app\EFM32PG12_STK3402\.includes_439041110852595a2173d174c3f79d80.txt -include BUILD_RELEASE\bootloader-app\EFM32PG12_STK3402\mbed_config.h -MD -MF BUILD_RELEASE\bootloader-app\EFM32PG12_STK3402\mbed-os\drivers\RawSerial.d -o BUILD_RELEASE\bootloader-app\EFM32PG12_STK3402\mbed-os\drivers\RawSerial.o .\mbed-os\drivers\RawSerial.cpp

If you look at the command you will recognize that -DHEADER_SIZE and -DHEADER_ADDR is defined twice.

I think the problem is a result from this mbed compile output:

Using regions in this build:
Region bootloader size 0xc800, offset 0x0
Region header size 0x10, offset 0xc800
Region application size 0x3fff0, offset 0xc810
Region header size 0x10, offset 0x4c800
Region post_application size 0xb37f0, offset 0x4c810

You can see that the Region header is there twice and I think that this is causes the warning.
