Hi,
I have just built (and installed) the following from the tutorials without any problems at all:
- Binutils 2.20 - i686-elf and x86_64-elf targets
- GMP 5.0.1
- MPFR 2.4.2
- GCC (C and C++) 4.4.3 - i686-elf and x86_64-elf targets
The host system was 1.7.1-1 on Vista with UAC disabled. I am the one who added the "Yes" for the GCC 4.4.2 configuration with Binutils 2.20, so I'm happy that works too (although that was on my XP box with Cygwin 1.5).
Perhaps you should delete all of you current builds, re-download Binutils, GMP, MPFR and GCC and retry. As the error seems to occur within on of the automake language files, I don't suppose your current source copy could be corrupted?
HTH,
Adam
