So when I try to run `make` I still get that error. Please note that I
am doing a VPATH build (the build in a separate directory from the
downloaded sources), which might play a role here:

x86_64-w64-mingw32-gcc.exe: error: libpqdll.def: No such file or directory
make[3]: *** [libpq.dll] Error 1
make[2]: *** [all-libpq-recurse] Error 2
make[1]: *** [all-interfaces-recurse] Error 2
make: *** [all-src-recurse] Error 2

I found a script that builds postgresql via MinGW-w64, and in it the
author specifically creates symlinks to libpqdll.def
https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-postgresql/PKGBUILD#L72
-- excerpt below:

# Make DLL definition file visible during each arch build
ln -s
"${srcdir}/postgresql-$pkgver/src/interfaces/libpq/libpqdll.def"
src/interfaces/libpq/
ln -s
"${srcdir}/postgresql-$pkgver/src/interfaces/ecpg/ecpglib/libecpgdll.def" src/interfaces/ecpg/ecpglib/
ln -s
"${srcdir}/postgresql-$pkgver/src/interfaces/ecpg/pgtypeslib/libpgtypesdll.def"
src/interfaces/ecpg/pgtypeslib/
ln -s
"${srcdir}/postgresql-$pkgver/src/interfaces/ecpg/compatlib/libecpg_compatdll.def"
src/interfaces/ecpg/compatlib/

Why are the symlinks needed to make the definition files visible?

Is this an issue with VPATH builds? It is not mentioned in the docs
where VPATH builds are discussed (section 15.4
http://www.postgresql.org/docs/9.5/static/install-procedure.html )

What is my best solutions?

Thanks!
