[avr-gcc-list] RFC: Libc versioning

[Svein E. Seldal]

Hi,

I am considering the ability to get the avr-libc version from an 
installed library. AFAIK this feature is missing. (If I'm wrong, please 
tell me where I can find it :) )

My initial suggestion will be to make a define in a header, similar to 
GCC's __GNUC__ and __GNUC_MINOR__:

#define __AVRLIBC__ xxx
#define __AVRLIBC_MINOR xxx

Any ideas of which file to put them in?

My secondary suggestion would be to be able to retrieve the avr-libc 
version from the installed libc.a - but still without being linked into 
the application (unless explicityly requested).

I can probably prepare a patch for libc for this, but I would like to 
discuss this with the community first.

Any comments or questions?


Regards,
Svein Seldal
