warning incompatible redefinition of macro "FLAG_Mask" and others

Rouse T

Hi,

I'm working in a project which uses some macros from Keil. These are RCC (so we use stm32f10x_rcc.c), SPI (stm32f10x_spi.c), DMA (stm32f10x_dma.c), PWR (stm32f10x_pwr.c), USART (stm32f10x_usart.c) and CEC (stm32f10x_cec).

When I compile the project, appears some warnings that say:

C:\keil_472\ARM\RV31\LIB\ST\STM32F10x_StdPeriph_Driver\src\stm32f10x_rcc.c(77): warning:  #47-D: incompatible redefinition of macro "CFGR_OFFSET" (declared at line 54 of "C:\keil_472\ARM\RV31\LIB\ST\STM32F10x_StdPeriph_Driver\src\stm32f10x_cec.c")
  #define CFGR_OFFSET               (RCC_OFFSET + 0x04)

I have put only an example, but for the following defines appear warnings:

FLAG_Mask
CFGR_OFFSET
CR1_CLEAR_Mask
CR_OFFSET
CSR_OFFSET

According to this thread: http://www.keil.com/support/docs/1727.htm I understand what is happening (the values of the defines are different for each one), but how I can solve it? what value the system will take in each case? all the same? the first that is defined?

Thanks for your attention
