We include <float.h> in every place that needs isnan(), because MSVC used to require it. However, since MSVC 2013 that's no longer necessary (cf. commit cec8394b5ccd), so we can retire the inclusion to a version-specific stanza in win32_port.h, where it doesn't need to pollute random .c files. The header is of course still needed in a few places for other reasons. I (Álvaro) removed float.h from a few more files than in Emre's original patch. This doesn't break the build in my system, but we'll see what the buildfarm has to say about it all.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
