GCC 4.2.1 : bootstrap fails at stage 2. Anyone know why ?

["Dennis Clarke" <dclarke at blastwave dot org>]

System is Solaris 8 Sparc.  Totally up to date.  Vendor provided compiler is
Sun ONE Studio 8 also patched up to date.

My boot strap of GCC 4.2.1 fails at stage 2.  Here is what I know.

My approach with GCC has always been to bootstrap at least twice and then
run the testsuites to verify that what I made was good.

I didn't even get to the first bootstrap before I hit a problem.

I make my own tool path and then build entirely with that toolpath. Within
reason. No need to create a new kernel and I do use libiconv from
Blastwave.org.  Only because I forgot to build it and at the last minute I
was too tired and it was too late so I put in

         --with-libiconv-prefix=/opt/csw

         on the configure line.

So here is what I did

I checked that I had sources to all the prerequisites :
    http://gcc.gnu.org/install/prerequisites.html

Thus I built and tested clean with :

    gmp 4.2.1
    gzip 1.3.12
    make 3.81
    bison 2.3
    m4 1.4.10
    mpfr 2.2.1

Each one of those passes all its tests with the exception of bison which
skipped 7 that required root level access or some such minutia.

Each of those was built with Sun ONE Studio 8 and I had the following
environment variables set :

TERM=vt100
SHELL=/usr/xpg4/bin/sh
CPPFLAGS=-I/export/home/dclarke/local/include
OLDPWD=/opt/build
LD_OPTIONS=-R/export/home/dclarke/local/lib -L/export/home/dclarke/local/lib
LC_ALL=C

I am using the bash shell and more specifically I am
using the latest release of bash.

The configure line for GCC 4.2.1 looks like so :

bash-3.2$ /export/home/dclarke/build/gcc-4.2.1/configure
--with-as=/usr/ccs/bin/as --without-gnu-ld --with-ld=/usr/ccs/bin/ld
--enable-threads=posix --disable-nls --prefix=/export/home/dclarke/local
--with-local-prefix=/export/home/dclarke/local --enable-shared
--with-libiconv-prefix=/opt/csw --enable-languages=c,c++,objc,fortran
--with-gmp=/export/home/dclarke/local --with-mpfr=/export/home/dclarke/local
--enable-bootstrap

Note that I am not using gas or gld and this is the way I have done this for
years. However, it has been years since I built GCC so who knows what error
I have made.

Also note that I restrict the languages to c,c++,objc,fortran for this
initial bootstrap. It should not make a whole lot of difference but I am
only interested in those.  For now.

The process seems to run fine and configure does what it does.  I issue make
( which is really GNU make that I built previously ) and things grind away
for a long long time until this appears :

checking for msgmerge... no
checking for sparc-sun-solaris2.8-gcc...
/opt/build/gcc-4.2.1-build/./prev-gcc/xgcc

checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run C

If you meant to cross compile, use `--host'.
See `config.log' for more details.

see this for all the details that follow :

Note that I do get a compiler from stage 1 but it seems unable to continue
onto stage 2 :

bash-3.2$ /opt/build/gcc-4.2.1-build/./prev-gcc/xgcc -v

So any thoughts there from anyone ?
