drivers/power/twl4030_charger.c:
#define TWL4030_BBSEL_3V0       0b0100
#define TWL4030_BBSEL_3V1       0b1000
#define TWL4030_BBSEL_3V2       0b1100

Werner, your gcc version is too old to support the 0b-prefixed binary
constant syntax.  It was introduced in gcc-4.3.  The kernel compiles
fine here, on gcc-4.7.

Neil Brown added this use of the 0b prefix in 210d4bc8a3128e3e61ac3b
("twl4030_charger: Add backup-battery charging").  Neil, I don't think
we can use this syntax yet -- Documentation/Changes says that we still
support from gcc-3.2 onwards.

Thanks,

- Chris.
