building 32bit windows version

I've been running into challenges building 32 bit windows version. I suspect there are no build farms and nobody really builds this.

The reason I need these is to be able to build 32 bit dll's for ODBC. At one time EDB used to provide binaries but that doesn't appear to be the case.

running build.bat in an x86 environment fails but that can be easily fixed by adding

$ENV{CONFIG}="x86"; in buld_env.pl

build postgres then works as advertised, however

install <dir> fails with

"Copying build output files...Could not copy release\zic\zic.exe to postgres\bin\zic.exe"

Apparently 32 bit dlls are required. If there is an easier way to get libpq.dll and the include files for building I'm all ears.
