Bootstrap error with gcc-20020429 snapshot on Sun / Solaris8

[glebourgeois@amadeus.net]

Machine: SunFire 6800 with Solaris 8.

config.guess output: sparc-sun-solaris2.8

BuildDir/gcc/xgcc -v output:
Using built-in specs.
Configured with: ../gcc-20020429/configure
--prefix=/softntools/tools/gcc-20020429 --enable-shared
--enable-threads=posix
Thread model: posix
gcc version 3.1 20020429 (prerelease)

Everything ran pretty well until configuring the boehm-gc which ended with
the following error:
loading cache ../config.cache within ltconfig
configure: error: libtool tag configuration failed
gmake[1]: *** [configure-target-boehm-gc] Error 1
gmake[1]: Leaving directory
`/softntools/softadm/Compilation/Build-gcc-20020429'
gmake: *** [bootstrap] Error 2

Anyone got any clue?

snapshot gcc-20020415 compiled fine, snapshot gcc-20020422 failed while
configuring Java.
I do hope gcc-3.1 release will bootstrap fine ('cause I need the gcc 64-bit
compiler!).
