            install command.
          + Fix problem with unwanted installation of assert.h on some
            systems.
          + Fix problem with finding the wrong assembler in a single tree
            build.

            removed in the next major release of G++. Use of signatures
            will result in a warning from the compiler.
          + Several bugs relating to templates and namespaces were fixed.
          + A bug that caused crashes when combining templates with -g on
            DWARF1 platforms was fixed.
          + Pointers-to-members, virtual functions, and multiple
            inheritance should now work together correctly.
          + Some code-generation bugs relating to function try blocks
            were fixed.

            to 1 digit
          + Fix missing std:: in the libstdc++ library.
          + Fix stream locking problems in libio.
          + Fix problem in java compiler driver.
       
   The whole suite has been extensively [1]regression tested and
   [2]package tested. It should be reliable and suitable for widespread
   use.
   
   The compiler has several new optimizations, new targets, new languages
   and other new features. See the [3]new features page for a more
   complete list of new features found in the GCC 2.95 releases.
   
   The sources include installation instructions in both HTML and
   plaintext forms in the install directory in the distribution. However,
   the most up to date [4]installation instructions and [5]build/test
   status are on the web pages. We will update those pages as new
   information becomes available.
   
   The GCC developers would like to thank the numerous people that have
   contributed new features, test results, bugfixes, etc to GCC. This
   [6]amazing group of volunteers is what makes GCC successful.
   
   And finally, we can't in good conscience fail to mention some
   [7]caveats to using GCC 2.95.1.

                                  GCC 2.95
                                      
   July 31, 1999
   
   The GNU project and the GCC/EGCS developers are pleased to announce
   the release of GCC version 2.95. GCC used to stand for the GNU C
   Compiler, but since the compiler supports several other languages
   aside from C, it now stands for the GNU Compiler Collection.
   
   This is the first release of GCC since the April 1999 GCC/EGCS
   reunification and includes nearly a year's worth of new development
   and bugfixes.
   
   The whole suite has been extensively [1]regression tested and
   [2]package tested. It should be reliable and suitable for widespread
   use.
   
   The compiler has several new optimizations, new targets, new languages
   and other new features. See the [3]new features page for a more
   complete list of new features found in the GCC 2.95 releases.
   
   The sources include installation instructions in both HTML and
   plaintext forms in the install directory in the distribution. However,
   the most up to date [4]installation instructions and [5]build/test
   status are on the web pages. We will update those pages as new
   information becomes available.
   
   The GCC developers would like to thank the numerous people that have
