Hi again, 

I don't understand this... when compiling my reuse-workspace, i indeed
obtain systematically errors that some library-predicates are not found
(like in this case the /, but also list__is_not_empty, and I suppose
other predicates too). These predicates are defined in the library
directory of the workspace, but indeed, are not yet within the
rotd-compiler that I'm using for compiling the workspace. 
But this makes the error even more strange: 
- the main-branch workspace which also uses those "new" library
  predicates compiles without a problem.. 
- so why does the reuse-workspace struggle with them? 

As I understand it, while compiling the compiler/-directory, it uses the 
library/- from the same workspace (or else I can't explain why my
main-branch workspace compiles). But for my reuse-workspace, it seems to 
use the rotd-library ? 

I can't see any significant differences in the makefiles... I simply 
don't have a clue... and simply don't know how to approach this problem


PS: just for the fun of it I installed rotd-2002-08-25.  Compiling the
main-branch, no problem, but compiling the reuse-workspace yields:
