This is a bit misleading, since GHC won't consult your PATH at link time, only at runtime. It might be better to phrase this as:
On Windows, zlib is shipped as part of GHC's mingw/lib directory, which GHC always includes in its linker search path. However, there is no guarantee that zlib1.dll (the corresponding shared library) will be available on the user's PATH at runtime, making it risky to depend upon (see #65 for what can go wrong). Thus, we resort to zlib-clib unless pkg-config is available.
Or something like that.

Thanks! I'll use the suggested wording.
