Many bugs have been fixed since the last release.
Some bugs surely remain.

Past releases of this library ran on a variety of configurations that are
no longer supported. Porting the library is not hard. If you are
interested in doing a port, please contact the glibc maintainers;
see http://www.gnu.org/software/libc/ for more information.
1995-02-18 01:27:10 +00:00
This release can be compiled using GCC 4.0, but you should expect many more
compiler warnings than using GCC 3.4. The development version of libc is
better suited to being built with the most recent GCC versions.
There are some add-ons which can be used together with GNU libc. They
are designed in a way to ease the installation by integrating them in
the libc source tree. Simply get the add-ons you need and use the
--enable-add-ons option of the `configure' script to tell where the
add-ons are found. Please read the FAQ file for more details.
1995-02-18 01:27:10 +00:00
See the file INSTALL to find out how to configure, build, install, and port
the GNU C library. You might also consider reading the WWW pages for the
GNU libc at http://www.gnu.org/software/libc/libc.html.
1995-02-18 01:27:10 +00:00
The GNU C Library is completely documented by the Texinfo manual found
in the `manual/' subdirectory. The manual is still being updated and
contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.
Please send comments on the manual to <bug-glibc-manual@gnu.org>, and
1995-02-18 01:27:10 +00:00
not to the library bug-reporting address.
The file NOTES contains a description of the feature-test macros used
in the GNU C library, explaining how you can tell the library what
facilities you want it to make available.
Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
information. We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.
1995-02-18 01:27:10 +00:00
