Помогите слинковать!

Проблема такая, есть некое АПИ к одной хрене в виде библиотек и хедеров соответственно, и мне нужно собрать либу с использованием этого апи...в результате вот такое получается:

g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -Wl,-s -shared -Wl,--out-implib,liblib.a -o "lib.dll" build\.obj\command.o build\.obj\connection.o build\.obj\date.o build\.obj\recordset.o "c:\libinterface.lib"

Как видно из вывода программа скомпилилась, но при линковке не находит точки входа функций, в библиотеке. Я говорил с разрабочиком апи он сказал, что проблема в формате имени функции и что нужно как-то по длл-кам собрать новую либу и подключить ее, но он не помнит как это делать..и вспоминать не хочет..\

ЗЫ
собираю все это под виндой + мингв.
