I reproduced the issue with ghc-7.8.3-x86_64. Are you using 64-bit ghc? If so, it looks the issue is 64-bit only.
Actually both _tzset and tzset exist in include/time.h, only tzset is old style name. They will be linked as the same function __imp__tzset.
What do you mean by "old style"? And more importantly, what foreign-import line shall be used that works both on Windows and non-Windows platforms, compiled as well as interpreted in GHCi?
I meant OLDNAME in MS's jargon, because they deprecate tzset [1], then call it 'old'. But it it still usable. [1] http://msdn.microsoft.com/en-us/library/ms235451.aspx -- cg
