A couple of days ago I posted to this list a problem but an attachment blocked forwarding due to size restrictions, pending a decision by a moderator. Heard nothing since then, so I'll point to this problem again without attaching config.log: I was able to compile rsync 2.5.7 on Solaris 8 Sparc without hassles using Sun's cc. The configure script for 2.6.0 fails because various basic data types are not found during configure, for instance pid_t. Uwe
