gperf-2.7 is released

[Bruno Haible]

gperf version 2.7 is on ftp://ftp.gnu.org/pub/gnu/ .

New in 2.7:

* gperf is now a stand-alone package, untied from libg++.
* Autoconfiguring.
* Removed the "-a" and "-g" options, extended the "-L" option instead.
* Removed the "-p" option, it is the default.
* Added long options ("--help", "--version" etc.).
* 8-bit cleanliness is now the default; use "-7" to get the old behaviour.
* Compiles with any C++ compiler.
* Numerous small improvements.

H.J., you can now drop gperf from libg++.

This is a libg++ addon for libstdc++ 2.8.1 and egcs. It is needed only
if your applications depend on libg++ and the dependency on libg++
cannot be removed easily. The standalone libg++ is not longer needed.

Changes from libg++ 2.8.1 980415:

1. gperf is removed from libg++. The stand-alone gperf is available at

ftp://ftp.gnu.org/pub/gnu/

The current version, as of May 5, 1998, is gperf 2.7.

The libg++ and librx have been tested with

1. egcs 1.0.2 on linux/x86/libc 5, linux/x86/glibc 2.1 and
   linux/alpha/glibc 2.0.7.
2. gcc 2.8.1 980209 and libstdc++ 2.8.1 980228 on linux/x86/libc 5.

It is available at

ftp://ftp.yggdrasil.com/private/hjl/libg++-2.8.1-980505.tar.gz
ftp://ftp.kernel.org/pub/linux/devel/gcc/libg++-2.8.1-980505.tar.gz

Patch for libg++ 2.8.1 980415 is also available at

ftp://ftp.yggdrasil.com/private/hjl/libg++-2.8.1-980415-980505.diff.gz
ftp://ftp.kernel.org/pub/linux/devel/gcc/libg++-2.8.1-980415-980505.diff.gz

Just put libg++ and librx under the egcs or libstdc++ source directory,
i.e.,

# cd src/egcs
# gzip -dc xxxxxx/libg++-2.8.1-980415-tar.gz | tar xf -

Or

# cd src/libstdc++-2.8.1
# gzip -dc xxxxxx/libg++-2.8.1-980415-tar.gz | tar xf -

Potential problems with libstdc++ 2.8.1:

1. Since gcc 2.8.1 is installed under /usr on Linux/GNU, libstdc++
   should be modified to reflect it. Otherwise incorrect header files
   and libraries may be used. A patch is available upon request.

You also need to check configure.in and configure to see if the
patch enclosed here is already applied. If not, please do

# patch -p0 < README.libg++

Then you can configure/build/check/install egcs normally. Now it
will include libg++.
