SPI_CLOCK_DIV64 is redifined

GoogleCodeExporter commented 9 years ago

In SPI.h, SPI_CLOCK_DIV64 is defined twice. Below is the code from SPI.h.  It 
is defined as 0x02, and then redifined as 0x07.

#define SPI_CLOCK_DIV4 0x00
#define SPI_CLOCK_DIV16 0x01
#define SPI_CLOCK_DIV64 0x02
#define SPI_CLOCK_DIV128 0x03
#define SPI_CLOCK_DIV2 0x04
#define SPI_CLOCK_DIV8 0x05
#define SPI_CLOCK_DIV32 0x06
#define SPI_CLOCK_DIV64 0x07

I'm writing CMake build scripts to compile the arduino code into static 
libraries.  This was the compiler warning:

In file included from 
/home/devind/Projects/Arduino/src/Ethernet/utility/w5100.h:14:0,                

                 from /home/devind/Projects/Arduino/src/Ethernet/Ethernet.cpp:1:
/home/devind/Projects/Arduino/include/SPI/SPI.h:25:0: warning: 
"SPI_CLOCK_DIV64" redefined
/home/devind/Projects/Arduino/include/SPI/SPI.h:20:0: note: this is the 
location of the previous definition

I'm using the arduino-0022 code on Gentoo Linux, but the OS doesn't really 
matter.

I can confirm this, i wasn't sure which one was actually correct. But i 
commented the bottom one out.
