I ran the following code to create the symbol list from zlib1.dll, and indeed the symmbol inflateGetHeader is included in zlib1.def. I also created libzlib1.a

I can only think that a different zlib1.dll (one that doesn't export that function, and is elsewhere in your PATH) has been loaded.

Try renaming the zlib1.dll in C:/Tcl/bin to (eg) zlib1.dll_hide, and see if that makes any difference to the errors you're getting.
If it does make a difference, then that means that the C:/Tcl/bin/zlib1.dll is probably the dll that was being loaded. But if it makes no difference, then there's probably another zlib1.dll that's being loaded.

The import lib you subsequently created is not needed as the build (dmake) stage did not contain any code that directly referenced any zlib functions, and the Tcl dll will automatically load the zlib functions (if they're present in the zlib dll).
If that import lib had been needed then the 'dmake' stage would have failed initially.

Cheers,
Rob
