However, they do know about the mingw build tools. In particular, from:
http://oldwiki.mingw.org/index.php/dllwrap
"dllwrap is a tool to build DLLs. It seems to be deprecated in favour of
gcc -shared option, but some projects still use it. SQLite, for example."
Armed with this information, it may be prudent review the DLL build
process in PGXS.
For the record: I originally asked the mingw-w64 team for help to link
against the 64bit JVM.DLL for which there was no corresponding .def file.
