GNU plotutils on RH8.0

[Nikolai V. Tkachenko]

Dear Robert Maier,

I have just installed plotutils on my Red Hat 8.0 Linux box.
My compiler version is gcc-3.2-7, and it took me a while
to install it. So I'd like to report what I did to get it up.

In short, after "make", error massage:

c++ -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/X11R6/include -I./../include
-DLIBPLOT -DLIBPLOTTER -O2 -c g_write.cc  -fPIC -DPIC -o
.libs/g_write.lo

                 from g_write.cc:5:
/usr/include/c++/3.2/backward/backward_warning.h:32:2: warning: #warning
This file includes at least one deprecated or antiquated header. Please
consider using one of the 32 headers found
in section 17.4.1.2 of the C++ standard. Examples include substituting
the <X> header for the
<X.h> header for C++ includes, or <sstream> instead of the deprecated
header <strstream.h>. To disable this warning use -Wno-deprecated.

   unsigned char*)':

make[2]: *** [g_write.lo] Error 1

Corrections made for "deprecated or antiquated header" is:

in include/plotter.h, line 61
#include <backward/iostream.h>
// certainly, 
// #include <iostream>
// should be done, and "using std" to be added, but I am lazy :)
// actually there are many warnings of this type...

then in libplotter/g_write.cc, line 43
    data->outstream->write(reinterpret_cast<const char*>(c), n);

// I suppose type of stream should be changed somewhere before...
 
The rest of errors are about the same:

However, after "make install" it works! Thanks for the package!
