1. The name is deflateSetHeader (case sensitive)

2. Do you really use it in your code?

3. You can take zlib1.dll from other distributions, e.g. from GIMP.
Overwrite the original in C:\GtkAda\bin and see what happens.

4. There is libz.a in C:\GtkAda\lib. You could link statically to it.

P.S. Use

   dumpbin.exe /exports foo.dll

to see the symbols exported from a DLL.
