With Cygwin DLL 1.5.25 (and the changes to 'tz...', I suppose), building 
Emacs from CVS gives this warning:

...
gcc -c  -Demacs -DHAVE_CONFIG_H -DUSE_LUCID  -I. -I/tmp/emacs/src 
-I/usr/X11R6/include    -g -O2 -Wno-pointer-sign  /tmp/emacs/src/strftime.c

/tmp/emacs/src/strftime.c:58: warning: '_tzname' redeclared without 
dllimport attribute: previous dllimport ignored
...

Could someone verify it and, eventually, apply ?
