[avr-libc-dev] [bugs #12134] ADC register name definitions

[Joerg Wunsch]

Follow-up Comment #1, bugs #12134 (project avr-libc):

I remember an old discussion that the use of ADC was

deprecated as it might conflict with the assembler

instruction named ADC (add with carry).  As <avr/io.h> is

supposed to be includable into assembler sources, any

#define for ADC would shadow that instruction.



One solutions would be to deprecate the ADC alias, but enable

it for !assembler compilations until it will eventually be

phased out.
