Where is the DLL file that exports these functions?

Question

I have been tasked with controlling a DAQCard E-series via program written in C. My development environment is MinGW on Windows 2000, with DAQ-MX and Traditional installed.
I started by using the MX example code as a foundation. Everything goes well it comes time to link the code; the linker can't find the exports defined anywhere.
E.g.: WriteDigPort_Fn.o : undefined reference to 'DAQmxCreateTask@8'
WriteDigPort_Fn.o : undefined reference to 'DAQmxCreateD0Chan@16'
etc.
(Same with the Traditional example, since it's using the same NIDAQmx.h header file)
My guess is these are properly defined in the (MSVC) .lib file supplied, but MinGW doesn't like it. I can build a definition file for this DLL that Min
GW will like, but to do this I need to know, what is the name of the DLL file these functions actually are exported from?
PS: Not part of my question, but for everyone searching here for info on NI DAQ + MinGW: MinGW defines 64-bit integer types using 'long long' instead of 'int64'. If you're getting errors referring to int64/etc., change the following lines in NIDAQmx.h:
//typedef __int64 int64; // replace this
typedef long long int64; // with this
//typedef unsigned __int64 uInt64; // and this
typedef unsigned long long uInt64; // with this

Greetings,
The NI-DAQmx ANSI C functions are contained within nicaiu.dll. This DLL should be available in the following location:
C:\WINDOWS\system32
Good luck with your application.
