The thing that caught me is that I have built GCC hundreds of times on i686/x86_64 with shared, private dir gmp/mpfr/mpc without a problem, so I went ahead and did the same on this machine; I normally bootstrap on my two main machines the 4.6 trunk every other day. Of course I am not claiming I didn't do anything wrong, just that it was not obvious from the various docs, including platform notes, that it was safer to use disable-shared or build from the GCC source tree. Anyway, my problem is fixed, and I know a bit more than yesterday; thanks everybody. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45482

How did you configure those prebuilt gmp/mpfr/mpc libraries installed under your home directory? In particular, did you configure them all with --disable-shared? If not, then you have to be extremely careful to avoid unintended mismatches, and in some cases incorrectly duplicated state. I know for a fact that prebuilt gmp/mpfr/mpc installed in a private location works fine on powerpc64-linux when all are configured with --disable-shared. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45482

--- Comment #10 from sfilippone at uniroma2 dot it 2010-09-08 15:35 --- (In reply to comment #9) > I have found a cure. The original configuration had GMP, MPFR and MPC built and installed under the user home directory (there were neither mpfr nor mpc system-wide, and gmp was a bit old); somehow this is the root cause of the problem, despite --with-gmp and friends. Building the three packages from source in the GCC source tree gets the bootstrap process beyond the previous stopping point (currently in middle of stage 3). Maybe this should be added to the platform-specific notes? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45482

Modifying the conftest source gives the following:
[snfi...@josquin libiberty]$ sh cmd.sh
[snfi...@josquin libiberty]$ ./conftest
Failing index 97 a
Reason: islower 2 ISLOWER 0 toupper A TOUPPER a
So the ISLOWER macro is (apparently) giving the wrong result.

According to the log in comment #4 this outputs 2 in your setup. It should
output 0. Can you find out why? You might want to replace '-o conftest' with
-E to see preprocessed output, maybe some bogus header somewhere.
Thanks.
