More likely, it's not finding the right one. Probably it's picking up
some completely different version of it because it's earlier in the
search path.

Is mingw even fully supported on 64-bit today?

64-bit PostgreSQL builds isn't - it "should just work", but I don't
believe anybody has ever tried it. But this error shows a much more
fundamental problem than the PostgreSQL code, and you need to get that
solved first.


Any particular reason why you don't want to build with the supported
toolset, which is the Microsoft (free) compilers? (See
http://www.postgresql.org/docs/9.0/static/install-win32-full.html)
