That was an error, however we are using symbol versioning completely = wrongly in FreeBSD anyway (see the last two DevSummit discussions and = the wiki page). New entries should *always* go in the version 0 = namespace (so that when they're MFCd the changes Just Work=99) and only = ever be moved out of there when they are replaced with versions with = different semantics. The weird hybrid we have that tries to conflate symbol versions and OS = releases manages to get the worst of both worlds. I've now moved it to the FBSD_1.3 namespace, but I would be more in = favour of going with the consensus from the last DevSummit and using = symbol versioning properly and move them all into the FBSD_1.0 = namespace. > Also, the ABI of the libc now depends on the compiler which was used = to > build the library, which is also wrong and ugly. No it doesn't. Read the patch. David
