[avr-libc-dev] Time after time

[Michael Rice]

I think I will back off now, and wait for feedback.

The time functions compile with  " -Wall -Wextra -Werror -pedantic ",  
under 4.3.2 and 4.7.2

I saw a bugzilla report that 4.8 apparently does not like my usage of  
_MEMX in strftime(). Since I have not yet built the 4.8 toolchain, I  
have no insight, but it appears to be an issue with 4.8 itself.  
However, I am keeping watch on the issue.
