It could be that libgmon.a can't be linked into a shared library.

(I deal with this all the time on HPUX; it's basically impossible to get
any profiling data about shared library add-ons.  However, you can
install your profilable postgres executable into a matching installation
tree built without profiling, and go from there.  The data about the
core system will all be fine --- its basically just the PLs and encoding
conversion that you can't measure.)

Theory B is that it's one of those symbol-visibility issues that we've
seen before.  Don't recall how to fix that on Windows though.
