Package: gcc-avr
Version: 1:4.7.2-2
Severity: normal

Hi,

in the deprecation handling in the AVR libc, a preprocessor symbol is
looked for with the new name first, then with a deprecated name that is
poisoned, with a construct similar to

#pragma GCC poison bar
#define foo
#if defined(foo)
#elif defined(bar)
#else
#endif

gcc-avr complains about this construct as the check in #elif references
"bar", but as it can never be taken, this is pointless.

The avr-libc bug report showing the (IMO valid) use case is #719635.

The same behaviour can be observed in mainline gcc and clang.
