djvu 3.5.16 doesn't compile on gcc 4.1. First it bails out with some "extra qualification in C++ headers" errors (easy fix, in djvu-3.5.16-gcc41.patch that I'll attach), but after solving that is fails with the error below. After looking in GContainer.h and related files, is seems that gcc just can't find the right hash-function, they are defined in GContainer.h, at the end. Instead it insists in using a hash()-function declared in GPixmap.h, that only takes a const DJVU::GPixel&. I solved this by moving the hash()-functions in GContainer.h to the front of the file, so gcc takes the right one. I put this patch in djvu-3.5.16-gcc41-hash.patch, this makes reproducing a bit more easy. And I'm not sure if this last error is gcc 4.1 specific.

Created attachment 78405 [details, diff] djvu-3.5.16-gcc41-hash.patch
I have added your two patches, but could you please report the problem (possible with your patches) upstream? It would be much better for them to fix the problem in the next release than us having to patch. Thanks for your report and for fixing it!
Of course, I submitted the bugreport and patches upstream: http://sourceforge.net/tracker/index.php?func=detail&aid=1420522&group_id=32953&atid=406583
