Cool, thanks for the patch.  Unfortunately it doesn't apply cleanly.
There are several unexpected line wraps and there's this:

How did this happen?  If you checkout the newlib-cygwin git repo,
strftime.c is under newlib/libc/time, not under newlib/time :o

Would you mind to attach a patch generated with git format-patch?


Thanks in advance,
