Some more data: I compiled gcc-3.4.2, rebuilt the libc, and now the compilation fails with the following. I guess 3.4.2 is not yet ready for prime time. I'll try again with 3.3.4, and finally again with 3.2.3 and the latest patch from CVS. -- 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=0x4182565fL 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).
