parallel threads on win32. [William Rowe] *) Correct a bug in determining when we follow symlinks. The code expected a stat -1 result, not an apr_status_t positive error. Also check if the APR_FINFO_USER fields are valid before we follow the link. [William Rowe] *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to mpm_common.c. These functions are only valid on some platforms, so they should not be in the main-line code. [Ryan Bloom] *) Remove ap_chdir_file(). This function is not thread-safe, and nobody is currently using it. [Ryan Bloom] *) Do not try to run make depend if there are no .c files in the current directory, doing so makes 'make depend' fail. [Ryan Bloom] *) Update highperformance.conf to work with either prefork or pthreads mpms. [Greg Ames] *) Stop checking to see if this is a pipelined request if we know for a fact that it isn't. Basically, if r->connection->keepalive == 0. This keeps us from making an extra read call when serving a 1.0 request. [Ryan Bloom and Greg Stein] *) Fix the handling of variable expansion look-ahead in mod_rewrite, i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of more complicated nested RewriteMap lookups. PR#7087 [Tony Finch] *) Fix the RFC number mentioned when complaining about a missing Host: header. PR#7079 [Alexey Toptygin ] *) Fix an endless loop in ab which occurred when ab was posting and the server dropped the connection unexpectedly. [Jeff Trawick] *) Fix a segfault while handling request bodies in ap_http_filter(). This problem has been seen with mod_dav usage as well as with requests where the body was just being discarded. [Jeff Trawick] *) Some adjustment on the handling and automatic setting (via hints.m4) of various compilation flags (eg: CFLAGS). Also,
