When you said that the reason you had not upgraded was because
my client runs on BeOS, and the configure support there is not
working "out of the box"
I assumed you meant that you had trouble building Subversion because
./configure did not work. However, given your answer above I deduce
that you didn't mean that, but rather that you have a run-time problem

1. There is no call to svn_path_join in svn_config_read_auth_data.
2. It is valid to pass a NULL config_dir to svn_config_read_auth_data,
so it should not cause a crash.

It's the wrong thing to do.
Does BeOS support the APR functions apr_uid_current, apr_uid_name_get,
apr_uid_homepath_get? If it doesn't then svn_config__user_config_path
will return a NULL path. The function auth_file_path in config_auth.c
doesn't handle the NULL (it also leaks any error returned by
The auth stuff appears to assume that the users config area will
always be available, which conflicts with the documentation for
svn_config__user_config_path which says that it may return NULL.
