I don't know a lot about the mspgcc and various chip support but:

1)  "`$' as a logical line" you can avoid to patch your compiler and use a 
standard compiler by adding in the msp.rules file  (i.e. 
tinyos-2.x/support/make/msp/msp.rules ) 


PFLAGS += -fnesc-separator=__
AMADDR = ActiveMessageAddressC__addr
and removing the line :
AMADDR = ActiveMessageAddressC\$$addr

You will need a nesc >= 1.2.8
You can do the same for the avr toolchain and it's even expected to become the 
default at some point in time 


2) it looks like you have a problem with msp libc includes, 
you can build with gcc/ld/as  in verbose mode using:
CFLAGS=-v make symsat
and compare it with 
CFLAGS=-v make telosb
It proved to be very helpful to me to track this kind of problems 

Best,
Aurélien
