OK. I get your point:

My app requires "SetupDiGetClassDevs()". When compiled, it generates a
reference to "SetupDiGetClassDevsA@16" *or* "_imp__SetupDiGetClassDevsA@16"
(depending on wheter og not I edit the original MS setupapi.h file, where I
remove the #define WINSETUPAPI DECLSPEC_IMPORT setting or not).

Now, the MS provided setupapi.lib, however, defines these symbols as:
"_SetupDiGetClassDevsA" and its imported reference as
"__imp__SetupDiGetClassDevsA". That's why it isnt working.

So the fix to this problem is either: 1) I need to generate a libsetupapi.a
which uses the GNU naming method somehow. Or 2) tell the GNU compiler not to
use the '@16' postfix-scheme on this specific library/dll. Correct?
