[egcs-1.1.2-pre3] boostrap failure on solaris-2.6

[Gabriel Dos Reis]

bootstrap of egcs-1.1.2-pre3 fails on solaris-2.6. I think this
failure is due to configure.

configure options:
=================

poivre% ../egcs-1.1.2-pre3/configure --prefix=$HOME --enable-shared --enable-haifa --with-new-abi --enable-languages="c c++" --verbose

bootstrap options: none
=================
