------- Comment #3 from baraclese at googlemail dot com 2008-02-24 21:22 ------- Apparently an old mpfr lib was the problem.
configure did warn me about it but said it was still okay afair. I switched from mpfr-2.2.1 to mpfr-2.3.0 now and it bootstrapped okay. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35354
