Do you have real evidence for that? We use 10 hex digits, yielding 2^40 combinations, so a 2^20 (one in a million) chance of collisions. I think it is more likely that there is some kind of bug going on, given the state of the build system. -- Han-Wen Nienhuys - [email protected] - http://www.xs4all.nl/~hanwen _______________________________________________ lilypond-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/lilypond-devel
