When the client library of PostgreSQL is compiled with a MinGW-w64
environment the resulting libpq does not work. This has been reported
upstream with two bug reports and a patch was submitted by
Michael Cronenworth <mike(at)cchtml(dot)com> (1) but it has not been
picked up by upstream.
This is confirmed to build on Arch Linux x64 with targets:
x86_64-w64-mingw32.static and i686-w64-mingw32.static
and works under Wine, Windows 7 and Windows 10 (both 32/64bit binaries)
