error in use of qsort
the files lib/sharedbook.c, lib/psy.c and lib/lsp.c use the c function qsort with wrong argument function. The compare functions sort32a, apsort and comp return a value not zero even if the compared values are equal. with my compiler (watcom 11.0a) the decoder hangs in qsort called in lib/sharedbook.c. if an extra compare is added, all is fine.
