More information: This thing is addressed in RVCT 4.0 Compiler Reference Guide:

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0348c/Babjddhe.html

"A plain bitfield, declared without either signed or unsigned qualifiers, is treated as unsigned. For example, int x:10 allocates an unsigned integer of 10 bits."

However, there is also flags like "--signed-bitfields" to change the behavior.
