Dev - C++ - Error al enlazar librerias en VC++

Hola a todos, tengo un problema al intentar crear una librería de enlace dinámico Win32, un dll en Visual C++. Al compilar no me da errores, pero al darle al botón de BUILD, comienza el problema, y es que no sé que le puede pasar para que me dé esos errores que muestro más abajo:

dll.dll - 16 error(s), 17 warning(s)

Espero que alguien me pueda aconsejar sobre qué librerías debo poner, quitar, o que configuraciones debo tocar para que el fichero dll se me ejecute correctamente y pueda crear la dll, de modo que la pueda usar para mis propósitos específicos.

Un saludo, y espero que alguien me pueda ayudar lo antes posible ya que no le encuentro solución, llevo varios días con este tema y estoy un poco amargado , jejeje, y es un poco urgente.....

Gracias de antemano....

Este error me aparece al iniciar el windows, al cargar todos los programas.
dice asi: C:WINDOWSSYSTEMSISTRAY.EXE A device attached to the system in not functioning.
Junto con este error aparece otro que dice:
The MSVCRT.DLL file is linked to nissing export MSVCRT.DLL:???@YAPAXI@Z

Tengo instalado windows 98 version ingles.

Que puede ser??....
