Okay, after running make edit_cache 't' has to be pressed to get the advanced mode where the OPENGL variables are, and then I added /usr/lib/libGL.dll.a and /usr/lib/libGLU.dll.a to those variables (separated from the /usr/lib/w32api libs by semicolons).  Then 'c' for configure and 'g' for generate, and then it exits and everything builds fine.
