No, in the system headers, tzname is defined as

__MINGW_IMPORT char     *tzname[2];

The conflict is with the __MINGW_IMPORT, which is missing in the
extern declaration in strftime.h


I wonder why you need to redeclare tzname[] there, do header files not
already declare it on platforms where HAVE_TZNAME is defined?
