# Generic rule for compiling C files:

.S.o:

# "-x assembler-with-cpp" should not be necessary since this is the default
# file type for the .S (with capital S) extension. However, upper case
# characters are not always preserved on Windows. To ensure WinAVR
# compatibility define the file type manually.

# Generic rule for compiling C to assembler, used for debugging only.
