MinGW compiled client library

Hello,

When the client library (version 9.2.x) is compiled with a MinGW-w64 environment
the resulting libpq.dll will not function. This has been reported previously
with two bug reports, which have gone untouched.

Bug 8151:
http://www.postgresql.org/message-id/E1UbELM-0007NK-5L@wrigleys.postgresql.org
Bug 8162:
http://www.postgresql.org/message-id/E1UcLPd-0000L4-TI@wrigleys.postgresql.org

I have tried compiling with every option enabled and every option disabled. Does
anyone have any pointers or would anyone be willing to help solve this issue?

What environment does EnterpriseDB use to create their Windows binaries?

Thanks,
Michael
