I just saw that.  Yes it does.  I made a copy of the linker script and
removed the "-lc" from the GROUP command.  I also saw "-lgcc" so I am
not sure if I should remove that as well; leaving it for the time being.

Once I removed "-lc" it seems that Newlib is not longer getting
included, but now instead of warnings, I am getting errors:

GNU ld (Sourcery G++ Lite 4.2-125)
2.18.50.20080215CMakeFiles/firmware.elf.dir/src/main.c.o: In function
`main':
/home/CorrinMeyer/versimation/sw/1.1/src/firmware/src/main.c:17:

start_c.c:(.text+0x6a): undefined reference to `__libc_init_array

Now line main.c:17 is actually a printf and it should be calling my
printf.  Not exactly sure why it is getting labeled as a reference to
'puts'.  I have no idea what the undefined "__libc_init_array" is.  Is
this a list of initialization functions that should be run by the C
library on start?
