Linking to library - what am I doing wrong?

Just installed Dev-C++, created a simple project test w/o linking to an external lib. Works fine.
Created second project, with directories specified for the external lib, added the lib itself into the build.
Linker errors - undefined references to those symbols in the lib I am trying to link. What am I doing wrong? Probably something simple. Thanks!
p.s. this is not a static lib - maybe that has something to do with it.

Here is the makefile.win:

Where did you get ../glut376/glut32.lib from? Did you build it yourself? If it is not a GNU library built specifically for MinGW, it will not work. The convention for GNU libraries os to have a .a extension, which is why I am suspicious.
There is some guidance in the " PLEASE READ BEFORE POSTING A QUESTION" thread on using OpenGL and GLUT with Dev-C++.
Post the build log.
