Hi John,

This looks like a known issue.

The .dll.a file is an import library which only contains a list of
symbols which are exported in the .DLL. The regular .a file is a static
library which doesn't care about exported symbols (iow: all symbols are
exported).

There are some bugs in zlib 1.2.3 which prevent some symbols from being
exported in the dll/dll.a files. One of the affected libraries of this
bug is the latest glib, see [1] for details. To fix this, I've updated
zlib to 1.2.5 in Fedora 14 and rawhide. I might update the zlib package
in Fedora 13 as well if there's a demand for it, but I don't have any
plans to update the Fedora 12 package as that release is reaching
end-of-life.

You can try to manually install the Fedora 14 package of mingw32-zlib
(which can be found at [2]) and see if the libxml2 build succeeds with
it.

Speaking of which, why are you building libxml2? We've already got a
mingw32-libxml2 package in Fedora which works fine. If you want to help
with maintaining the package, feel free to apply for it in pkgdb.
