hdlc.c:159: warning: concatenation of string literals with __FUNCTION__ is
deprecated
The compiler doesn't like the string concatenation in the asm
statement in iomacros.h:
#define _BIC_SR_IRQ(x)\
__asm__ __volatile__ (\
"bic %0, .L__FrameOffset_" __FUNCTION__ "(r1)"\
: : "i" ((uint16_t)x)\
)

Are you using gcc 4.x? With gcc4, the above macro isn't used,
but rather a built-in function that has been added to gcc itself.
