Remy, As for me, I'm using gcc 3.3.4 with our own patches, which I've submitted to this project patches. May be that might solve the problem. Or may be with patches by Dmitriy Dikiy. It may be wrong but it may work in our case. Who knows?

Funny you should mention that. I just compiled gcc-3.3.4, recompiled msp430-libc (had to remove a few part types that are not supported in the CVS patch), and I am able to compile the TinyOS application. With a load of warnings, though. The application still doesn't work on the target, but it is possible that this is a problem on my end. I forgot to mention in my original post that I was using gcc-3.2.3. The warnings are attached below, in case anybody has a suggestion as to what they mean (I don't know what 'strict-aliasing' means). -- Remy ncc -o build/wsnbase/main.exe -Os -I/home/joe/src/wsn/tinyos/tos/platform/wsnbase -I/home/joe/src/wsn/tinyos/tos/lib/XE1205Radio -fnesc-target=msp430 -gcc=msp430-gcc -mmcu=msp430x149 -Wall -Wshadow -DDEF_TOS_AM_GROUP=0x7d -Wnesc-all -target=wsnbase -fnesc-cfile=build/wsnbase/app.c -board= -DIDENT_PROGRAM_NAME="SenseBase" -DIDENT_PROGRAM_NAME_BYTES="83,101,110,115,101,66,97,115,101,0" -DIDENT_USER_HASH=0L -DIDENT_UNIX_TIME=0x41825d5aL SenseBase.nc -lm /opt/tinyos-1.x/tos/platform/msp430/MSP430ADC12M.nc:661:2: warning: #warning "This version of gcc might contain a bug which results in false accessing of bitfields in structs (MSP430ADC12M.nc will fail).
