Looking over the exported symbols between Unix (FreeBSD/ELF with nm -D) and Windows (the libtiff.def list), there are a lot of missing symbols on Windows. I've attached a list showing which are missing. Would it be possible to update the symbol list for 4.0.4? Some symbols are likely not supposed to be exported on Unix (expecially those without a TIFF or _TIFF prefix) and should probably be ignored.
Linux/FreeBSD/ELF exports all non-static symbols by default and this is usually unwanted. In this case, Windows is ahead of default ELF linkage. I do see at least one new symbol which should have been exposed for Windows.
