I'm sure that I have no left-over .o but maybe I'm too confident in the 
'make clean' command.

Anyway, after a closer look in the symbols the only critical 'gl' symbol 
seems to be gl__unused413. But you say the undefined reference you got 
was mgl__unused413 while in my case mgl__unused413 is well defined.

# nm lib/* | grep "gl__unused413"
00004b40 T mgl__unused413
          U gl__unused413
