      GNU g++,

      I have just sent you 3 g++ bug reports describing problems I have
run into over the past several months.  The compiler used was 2.95.2
running on Red Hat Linux, version 2.2.5-15 (as I recall, called release
6.2 by Red Hat).

      I had very much wanted to run these examples on the new gcc-3.1
but I was not able to install it.  I saw several "successful build"
reports for this compiler on the GNU web site but, so far, I can not
find the path to success.  I tried on a Red Hat 7.2 system, Linux
version 2.4.7-10.  First step was to obtain binutils-2.11.2 and build
and install that using all default configuration options.

      Then I got gcc-3.1. This I configured as follows --

      configure --enable-languages="c,c++" \
                --enable-threads \
                --disable-nls

      But, following this,

      make bootstrap

      produces --

else true; fi

      I'm stuck here.  Any advice would be greatly appreciated.  
Thanks.

PS:  In submitting these notices I realize that I have not followed your
guidelines exactly, in particular, your request that problems be
reported using GNATS.  The weakness is entirely my own -- this is a
"learning curve" consideration.  Hopefully, I will eventually come to
understand how to use the recommended methods.

      I would like to also say that I have been using g++ for a little
over three years now on various machines.  The existence of language
itself is a pure miracle in my opinion and if I were to be given the job
of handing out Nobel prizes I would give Bjarne Stroustrup one a year
for the next ten years.  But, unfortunately, there are a number of
problems with the implementations.  Yours appears to be, if not the very
top, certainly fantastic.  I wish I were in circumstances that permitted
me to be of more help than simply reporting problems but "free time"
seems to be something I encounter only in dreams.  Thank you for your
prodigious and tireless efforts to provide our community with this most
magnificent programming language.
