 ====== Unresolved issues ======
+**OUT OF DATE** most of these issues have been resolved or worked around, or were only relevant in the initial, experimental phase.
+===== --prefix =====
+You'll notice that I recommend installing several components (HDF, NetCDF, Grib...) in their own directories under ''/opt''.  The reason for this is that it makes it easier to clean up spills while working out the build process.  The downside is that although everything will //build// correctly, some components may fail to //run//
+**XXX is this really an issue?  perhaps we should just build static libraries.***
+===== Shared libraries =====
+Windows doesn't have transitive shared library dependencies.  What this means, in plain language, is that you can't assume&mdash;as you can on ELF systems&mdash;that loading a shared library automatically loads all of //its// dependencies.  Therefore, libtool will refuse to generate shared libraries unless you promise that whenever you load it, you will also load all of its dependencies.  To do that, you must
+  - place ''LDFLAGS=-no-undefined'' in your environment before running ''configure'', and
+  - manually load all the required libraries when you aren't using libtool
 ===== Compiler crash =====
