+GCC v3.3.4 / LIBC v0.6 - Alpha 2:
+---------------------------------
+
+    This release have been timebombed and will stop work at the
+    end of october 2004. The reason for this is that data structures
+    shared between LIBC 0.6 and all future LIBC versions are not yet
+    finalized.
+
+
+    New Features:
+
+        o Updated GCC to version 3.3.4.
+
+        o 2nd fork() implementation.
+          All binaries are by default forkable, use the link option
+          -Zno-fork to disable this.
+          The fork implementation rendered _rmutex useless and it
+          has been removed.
+
+        o Symlinks using EAs. This is work in progress. One of the
+          limitiations is that readir will not report DT_LNK yet.
+
+        o Unix compartment using chroot(). This offers a
+          redirection of '/' to the chroot'ed root. The entrance
+          to the compartment is the '/'. The exits are drive letters.
+          The unix compartment is inherited by LIBC child processes.
+
+        o getcwd() will now return the driveletter too (as VAC does)
+          when not inside the unix compartement.
+          _getcwdux() has been provided for porters which requires
+          behaviour like the old getcwd() implementation.
+
+        o Paths to unix files #defined in headers are now prefixed
+          with "/@unixroot" which will be redirected to where the
+          environment variable UNIXROOT points. After calling
+          chroot() the target of "/@unixroot" will be changed too.
+
+        o LIBC specific path rewriting (redirection). Built in is
+          "/dev/null", "/dev/tty" and "/@unixroot".
+          The environment variable LIBC_PATHREWRITERS is examined
+          during init and DLLs specified in it are loaded and called.
+          See src/emx/src/sys/pathrewrite.c for more details.
+
+        o Non-unix like mode - link option -Zno-unix.
+          This affects slashes and various other Unix-like features
+          like for instance fork and symlinks.
+
+        o Printf et al. have been extended to support some new format
+          specifiers. (It's still lacking a bit to be SuS comforming.)
+
+        o Sockets handles are now inherited by LIBC child processes.
+
+        o LIBC specific filehandle flags are now inherited by LIBC
+          child processes.
+
+        o The GCCxyz.DLL is no longer needed when LIBC is used.
+          However it is still shipped for special cases where LIBC
+          isn't needed.
+
+        o A good bunch of 'new' functions both from the SuS and from
+          various Unix flavors, even one or two PC functions have been
+          added. Accompanying these are new headers and header updates.
+          Here are most of the new function names:
+            __strverscmp(), _atfork_callback(), _getcwdux(),
+            _getdcwd(), _nsdbtaddsrc(), _nsdbtput(), _nsdispatch(),
+            _realrealpath(), canonicalize_file_name(), catclose(),
+            catgets(), catopen(), chown(), chroot(), eaccess(),
+            endgrent(), endnetgrent(), endusershell(), fchown(),
+            fstatfs(), fstatvfs(), getdtablesize(), getfsstat(),
+            getgrent(), getgrent_r(), getgrgid_r(), getgrnam_r(),
+            getloadavg(), getmntinfo(), getnetgrent(),
+            getpwent_r(), getpwnam_r(), getpwuid_r(), getrlimit(),
+            getusershell(), innetgr(), lchown(), link(), mknod(),
+            readlink(), setgrent(), setgroupent(), setgroups(),
+            setnetgrent(), setpassent(), setrlimit(),
+            setusershell(), sl_add(), sl_find(), sl_free(),
+            sl_init(), statfs(), statvfs(), strmode(), strtok_r(),
+            symlink() and sync().
+
+
+    Bug fixes:
+
+        o setlocale() have been rewritten. The code page is now
+          taken from the locale rather than OS/2. Old behaviour
+          is used if environment variable LIBC_SETLOCALE_OLDSTYLE
+          is defined.
+
+        o Buggy strspn() replaced by BSD implementation.
+
+        o Thread backend have been reworked fixing certain
+          problems when LIBC was loaded and initialized in threads
+          other than the primary one. A LIBC specific TLS api
+          was created during this effort.
+
+        o Fixed a missing export from GCCxyz.dll which was causing
+          incorrect behaviour of C++ exceptions in all previous
+          releases.
+
+        o Fixed a buffer overrun in iconv_open() which caused a
+          corruption of the FS selector register, thus crashing
+          the processing.
+
+        o ...
+
+
+    Known limitations and bugs:
+
+        o mktime() works incorrectly for exterme values causing
+          configure test to fail.
+
+        o NSS probably doesn't work.
+
+        o Trailing slashes of a path specification are not
+          handled correctly after the rewrite of the path
+          handling.
+
+        o New path handling is not DBCS ready.
+
+        o Socket handle duplication have not been implemented yet.
+
+        o The __<syscall> function are in the process of being
+          removed.
+
+        o Not tested with mozilla.
