To avoid it try produce import library by LIB.exe  utility program from VC6
instead of dllwrap.

You can use dll only in C language (not C++) because name mangling is
different in VC and GCC. That is your dll must
be compiled with gcc (or your export function must be defined as extern "C" ).
And so in your VC application definition of that functions looks something like:

extern "C"
__declspec(dllimport) void __cdecl my_function_from_dll();
