In the build output I remember seeing ./configure selecting o32.
But I didn't notice for which part of the build this was.
tools/gmp/build has:
java:/home/bouyer/tmp/i386/obj/home/bouyer/src/tools/gmp/build>file version.o 
version.o: ELF 32-bit LSB relocatable, MIPS, MIPS-I version 1 (SYSV), with 
unknown capability 0xf41 = 0x756e6700, with unknown capability 0x70100 = 
0x3040000, not stripped

mpfr config.log has:
configure:13596: cc -o conftest -O  -I/home/bouyer/tmp/i386/obj/home/bouyer/curr
ent/src/tooldir/include  -L/home/bouyer/tmp/i386/obj/home/bouyer/current/src/too
ldir/lib conftest.c -lgmp   >&5
ld: 
/home/bouyer/tmp/i386/obj/home/bouyer/current/src/tooldir/lib/libgmp.a(lt22-init.o):
 ABI is incompatible with that of the selected emulation

Sure: ftp://asim.lip6.fr/outgoing/bouyer/config.log.tar
contains all the config.log files under tools/

I didn't save the output of build.sh but I can restart a clean one if
needed.

I don't think it used -64, but maybe -o32 ...

OK, thanks
