OK, I'll note that in the instructions.

It looks like you can also enable this option as a one-off by passing
-use-full-path:

msys2_shell.cmd -use-full-path

Your quoting is wrong here - there's no closing quote on CXXFLAGS, so this
sets CXXFLAGS to the value:

    -EHsc AR=lib -IC:\zlib-1.2.3-lib\include LDFLAGS=-LC:\zlib-1.2.3-lib\lib

And then doesn't set AR, CPPFLAGS or LDFLAGS at all.

You're also missing CPPFLAGS= before -IC:\zlib-1.2.3-lib\include so
fixing both of those I guess you want:

./configure CC="cl -nologo" CXX="$PWD/compile cl -nologo" CXXFLAGS="-EHsc" AR=lib CPPFLAGS=-IC:\zlib-1.2.3-lib\include LDFLAGS="-LC:\zlib-1.2.3-lib\lib" --prefix="C:\xapian-install"

I don't think that's the cause of your immediate problem, but this will
cause you problems sooner or later.

Looking at the CI logs, it seems that xapian-core's configure there
finds GNU ld, but doesn't actually use it for the build:

https://ci.appveyor.com/project/ojwb/xapian/builds/22443660/job/muwq9r3jmcde4h92?fullLog=true#L844

So probably installing GNU ld from mingw would work around this, but
really you shouldn't need to have it installed as MSVC is used for
linking.

You could try adding LD=link to the configure command line (to tell it
to use the Microsoft linker).

Sorry for the bumpy ride here - it's definitely possible (as the CI
build shows) but this is fairly new and I don't think many people have
tried to replicate that using the instructions in INSTALL yet.
