Indeed, they were shared. 
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.

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.

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?

Modifying the conftest source gives the following:

[snfilip@josquin libiberty]$ sh cmd.sh 
[snfilip@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. 

---------------------------------------
#include <ctype.h>
#include <stdlib.h>
#include <stdio.h>
#if ((' ' & 0x0FF) == 0x020)
# define ISLOWER(c) ('a' <= (c) && (c) <= 'z')
# define TOUPPER(c) (ISLOWER(c) ? 'A' + ((c) - 'a') : (c))
#else
# define ISLOWER(c)                (('a' <= (c) && (c) <= 'i')               ||
('j' <= (c) && (c) <= 'r')                   || ('s' <= (c) && (c) <= 'z'))
# define TOUPPER(c) (ISLOWER(c) ? ((c) | 0x40) : (c))
#endif

#define XOR(e, f) (((e) && !(f)) || (!(e) && (f)))
int
main ()
{
  int i;
  for (i = 0; i < 256; i++)
    if (XOR (islower (i), ISLOWER (i))
        || toupper (i) != TOUPPER (i)) {
      fprintf(stderr,"Failing index %d  %c \n",i,i);
      fprintf(stderr,"Reason: islower %d  ISLOWER %d  toupper %c TOUPPER %c
\n",
              islower(i),  ISLOWER (i),
              toupper (i) , TOUPPER (i));

Indeed.

2

Output attached. I have no more time to look at it now, will get back
tomorrow morning (my time)

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.
