+his is the release of the Linux C library 4.2. You have to
+install the source code of 0.98 pl5 to use it since fd_set is changed
+and it needs <linux/ioctl.h>. You don't have to use 0.98 pl 5 kernel.
+But 0.98 pl 4 kernel is necessary. You also need gcc 2.3.3 or above to
+use it.
+
+Since kernel now has the 387 emulation, we don't need soft math library
+anymore.
+
+I was told this shared image work with older kernel (newer than 0.97
+pl4). I have put libnet.a and librpc.a back into libc.a.
+
+Please get the latest binutils.TZ from tsx-11.mit.edu if you cannot
+get your binaries linked with the shared libraries. Starting with this
+release, I used a new structure for libraries.  The different versions
+of each library, i.e., static, jump table and classic shared library,
+are in the same directory, /usr/lib.  To illustrate, if the library is
+named foo, then the static version is libfoo.a.  The jump table version
+is libfoo.sa and the classic version is libfoo.ca.  The new `ld', which
+is in binutils.TZ and on the third disk of the Linux Base System on
+tsx-11.mit.edu, searches for the jump table library by default.  You
+can overwrite it by adding -static or -nojump to `ld' or 'gcc'.  The
+jump table and classic versions are not compatible with each other.
+The static library should be used as a last resort. You can rename your
+old shared libraries, notablely Xfree386, to fit the new scheme. The
+script should look something like that:
+
+----------
+#!/bin/sh
+
+cd /usr/X386/lib
+for l in shlib/jump/*
+do
+  s=`basename $l .a`
+  mv $l $s.sa
+done
+for l in shlib/nojump/*
+do
+  s=`basename $l .a`
+  mv $l $s.ca
+done
+----------
+
+Please make sure it works right before you run it.
+
+You can get them from tsx-11.mit.edu under pub/linux/GCC. The
+file names are image-4.2.TZ, extra-4.2.TZ, gxx-2.3.TZ, inc-4.2.TZ,
+jump-4.2.TZ and libc-4.2.TZ.
+
+Please read ChangeLog for details of the bug fixes.
+
+The file list:
+
+1. image-4.2.TZ
+
+  The shared images and libraries. To install it, as root do
+
+  cd /tmp
+  rm -rf ./lib ./usr
+  tar xvvofz image-4.2.TZ
+  cp -av ./lib ./usr /
+  cd /lib
+  ln -sf libc.so.4.2 libc.so.4
+
+  If you have an early version of libc.so.4.2 installed, you may have
+  to play with it, like
+  
+  cd /lib
+  cp libc.so.4.2 libc.so.4.2.old
+  ln -sf libc.so.4.2.old libc.so.4
+  mv libc.so.4.2 foo
+
+  before you unpack image-4.2.TZ. The iostream is in libc.so.4.2. But
+  you have to use -nojump to use it since the external interface of
+  iostream may change in the future.
+  
+2. extra-4.2.TZ
+
+  libg.a and libc_p.a. To install
+   
+  cd /
+  tar xvvofz extra-4.2.TZ
+
+  libg.a is very big. I usually do
+
+  cd /usr/lib
+  ln -s libc.a libg.a
+
+  since I usually do not debug the C library this way.
+
+3. gxx-2.3.TZ
+
+  libg++.a, g++-include and genclass. It is libg++ 2.3. To install
+
+  cd /usr
+  tar xvvofz gxx-2.3.TZ
+
+  Iostream is in libc.a. To use it, you have to use -nojump
+  or -static in your LDFLAGS.
+
+4. inc-4.2.TZ
+
+  To use the 4.2 header files, do
+
+  cd /usr
+  tar xvvofz inc-4.2..TZ
+
+  /usr/include/asm and /usr/include/linux may be wrong. Please make
+  a right symbolic link to each of them according to your Linux kernel
+  source tree.
+
+5. inc1229-4.2.TZ
+
+  Change of the header files from 1129 to 4.2. It is in the testing
+  directory.
+
+  cd /usr
+  tar xvvofz inc1229-4.2.TZ
+
+6. jump-4.2.TZ
+
+  There is also a file called jump-4.2.TZ for building the shared
+  image for the C library 4.2. Please install image-4.2.TZ first since
+  you need libgcc.a in it. The has been changed a lot thanks to
+  dje@sspiff.cygnus.com (Doug Evans).
+
+7. libc-4.2.TZ
+
+  The source code of the Linux C library 4.2.
+
+8. libc1229-4.2.TZ
+
+  Change of the source code from 1229 to 4.2. It is in the testing
+  directory.
+
+9. ChangeLog
+
+  Change log for the Linux C library.
+
+10. inc-4.2-fix.TZ
+
+  Some fixed headers failed to make into inc-4.2.TZ but are needed.
+  To unpack it:
+
+  cd /usr
+  tar xvvofz inc-4.2-fix.TZ
+
+Please fix the file permissions after you install it.
