[avr-gcc-list] undefined reference to "exit" error

[Gary French]

I've built an avr compiler with binutils-2.17, gcc-4.2.0, and avr-libc (cvs as 
of 2007-09-15)

at90s1200, attiny11, attiny12, and attiny28 targets give the following error 
when compiling for assembly (where XXXX is the file specific to the device):

[...]avr/lib/crtXXXX.o: In function `__bad_interrupt':
../../../../crt1/gcrt1.S:124: undefined reference to `exit'

exit.o is in lib/avr25/libc.a and adding -lgcc does make this go away, but I'm 
not entirely sure I trust that it's the right one.

I'm aware that "XJMP main" was recently replaced with "XCALL main; XJMP exit" 
in gcrt1.S, could that be related?

any opinions or thoughts would be appreciated.
