It seems to work for CVS OpenJade as well (I can't say for sure, since
I first had to install gcc-2.95 and now it is still compiling, but
it already build libsp successfully).

But the patch fails if unsigned int != size_t, doesn't it ?
The CVS version of OpenJade needs more fixes for gcc-2.95 anyway. 
Here is another untested idea: Wouldn't it be enough to move the
potential duplicates to different files to avoid the conflict ?
