13 Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
14 Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
15 More if/def section may be needed to support other platforms
16 Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
17 (but you should use iowin32.c for windows instead)

26 // Linux needs this to support file operation on files larger then 4+GB
27 // But might need better if/def to select just the platforms that needs them.
