This is an announcement of DJGPP port of gcc-2.95.3 and some additional
packages:
GCC-2.95.3
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. It includes C, C++,
Objective-C and GNU Fortran compilers with corresponding libraries.
libg++-2.8.1.3
This is addon for current gcc release (e.g. gcc-2.95.3)
and libstdc++. It is needed only if your applications depend on
libg++ and you cannot easily remove the dependency on libg++.
The standalone libg++ is no longer needed. Note that this package
is no longer being maintained.
which are available from DJGPP distribution in Simtelnet
(and mirror sites) in directory v2gnu:
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu
For information what's new in gcc-2.95.3 and earlier versions see
http://gcc.gnu.org/gcc-2.95/gcc-2.95.3.html
http://gcc.gnu.org/gcc-2.95/gcc-2.95.2.html
http://gcc.gnu.org/gcc-2.95/gcc-2.95.1.html
http://gcc.gnu.org/gcc-2.95/gcc-2.95.html
There are 7 archives:
readme-gcc2953.txt - readme file from DJGPP port of GCC-2.95.3. It's in
separate file to avoid need to download large archives
to get this file.
gcc2953s.zip - sources of gcc-2.95.3 and libg++-2.8.1.3 for DJGPP.
I put all sources in a single archive. This file is only
needed if You're want to rebuild gcc-2.95.3 from sources.
gcc2953b.zip - binaries of C compiler
gpp2953b.zip - binaries of C++ compiler (needs gcc2953b.zip)
g772953b.zip - binaries of Fortran compiler (needs gcc2953b.zip)
objc2953.zip - binaries of Objective C compiler (needs gcc2953b.zip)
lgp2953b.zip - binaries and header files of libg++-2.8.1.3 (useless
without gcc2953b.zip and gpp2953b.zip). It's recommended
NOT to use libg++ in new projects.
gcc2953s2.zip - shell script and patches for original gcc-2.95.3 (and
libg++-2.8.1.3) sources. I used them to generate gcc-2.95.3
sources for DJGPP (later archived in gcc2953s.zip).
(Note that CHILL and JAVA compiler binaries are not made available as they
are not ready for general use, more exactly not tested at all. I don't know
when this will change. I don't have any plans in that direction)
Files user need:
Programming languages Needed files
C gcc2953b.zip
C++ gcc2953b.zip, gpp2953b.zip (and possibly also lgp2953b.zip)
Fortran gcc2953b.zip, g772953b.zip
Objective-C gcc2953b.zip, objc2953.zip
NOTE: gcc2953b.zip contains file cxxfilt.exe and there is file with same name in
binutils (bnu10b.zip). You can safely overwrite the old one.
For more information about this port see archive
gnu/gcc-2.953/readme.DJGPP
after unpacking either gcc2953b.zip or gcc2953s.zip or get file
readme-gcc2953.txt from directory v2gnu in DJGPP distribution
Also please DON'T mix C++ libraries (or object files) built with
different compiler versions. C++ sources should be recompiled (seems
that there is no need to do this for C sources).
System requirements
===================
DJGPP-2.03 or above (otherwise exceptions will not work at all)
binutils-2.10 or above (It's possible to use binutils-2.8.1 or 2.9.1 but
it is NOT RECOMMENDED and GCC command line option -mno-bnu210
is required. DJGPP port of gcc-2.95.3 generates warning
when option -mno-bnu210 is being used)
Some warning for users of C++. C++ compiler in gcc-2.95.3 does more strict
syntax checking than gcc and egcs versions older than gcc-2.95. As result
errors are generated in many places where earlier one got warnings.
DJGPP related updates since last update of DJGPP port of gcc-2.95.2
===================================================================
gcov.exe is also included in gcc2953b.zip. See gnu/gcc-2.953/readme.DJGPP
for more info
-mbnu210 is now default. It's recommended to stop using this option

Here is official announcement of gcc-2.95.3
March 16, 2001
The GNU project and the GCC developers are pleased to announce the release
of GCC version 2.95.3. 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 a minor release to address several bugs in the GCC version 2.95.2
release.
Generic bugfixes and improvements
Fix numerous problems that caused incorrect optimization in the register
reloading code.
Fix numerous problems that caused incorrect optimization in the loop optimizer.
Fix aborts in the functions build_insn_chain and scan_loops under some
circumstances.
Fix an alias analysis bug.
Fix an infinite compilation bug in the combiner.
A few problems with complex number support have been fixed.
It is no longer possible for gcc to act as a fork bomb when installed
incorrectly.
The -fpack-struct option should be recognized now.
Fixed a bug that caused incorrect code to be generated due to a lost stack
adjustment.
Platform specific bugfixes and improvements
Support building ARM toolchains hosted on Windows.
Fix attribute calculations in ARM toolchains.
arm-linux support has been improved.
Fix a PIC failure on sparc targets.
On ix86 targets, the regparm attribute should now work reliably.
Several updates for the h8300 port.
The whole suite has been extensively regression tested and package tested.
It should be reliable and suitable for widespread use.
The GCC 2.95 release has several new optimizations, new targets, new
languages and other new features as compared to EGCS 1.1 or GCC 2.8.
See the new features page for a more complete list of new features found
in the GCC 2.95 releases.
