The timezone variable has been around since 1997, but it's called
_timezone for historical reasons. Prior to 1.5.25 there was a
# ifndef timezonevar
char *timezone (void);
# elif !defined(timezone)
# define timezone _timezone
# endif
#endif /*__STRICT_ANSI__*/
so you have to `#define timezonevar' to get the timezone variable. The
problem is that this collides potentially with the definition of struct
timezone. 1.5.25 now defines timezone like this:
extern long timezone __asm__ ("__timezone");
In theory (and if the code doesn't use the struct timezone) the below
code should be portable and should work fine with any version of Cygwin:
#ifdef __CYGWIN__
#define timezonevar
#endif
#include <time.h>
[... use timezone variable ...]
