After getting the GNUARM installed, when I do a make I get the 
following output:

main.o(.text+0x10): In function `main':
/cygdrive/d/GNUARM/Projects/Vader/main.c:172: undefined reference to 
`Init_CPU'
main.o(.text+0x24):/cygdrive/d/GNUARM/Projects/Vader/main.c:198: 
undefined reference to `Init_Display'
main.o(.text+0x28):/cygdrive/d/GNUARM/Projects/Vader/main.c:293: 
undefined reference to `MA_ReadPort_GPIO'
main.o(.text+0x48):/cygdrive/d/GNUARM/Projects/Vader/main.c:294: 
undefined reference to `VaderData'
collect2: ld returned 1 exit status
NMAKE : fatal error U1077: 'arm-elf-gcc' : return code '0x1'
Stop.

The file listings contain this "/cygdrive/d" portion like:

/cygdrive/d/GNUARM/Projects/Vader/main.c

The true path should be:

D:/GNUARM/Projects/Vader/main.c

How do I define this /cygdrive/ variable so I can get accurate paths 
listed in the output?

Thanks,  Chris.
