Hello,

I caught the same issue with an unmodified gmp-4.2.1-rc.

The failed test is t-bswap.c:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I..    -m32 -O2 -fomit-frame-pointer
-mcpu=pentium3 -march=pentium3 -c t-bswap.c
/bin/sh ../libtool --mode=link gcc  -m32 -O2 -fomit-frame-pointer
-mcpu=pentium3 -march=pentium3   -o t-bswap  t-bswap.o libtests.la
../libgmp.la
gcc -m32 -O2 -fomit-frame-pointer -mcpu=pentium3 -march=pentium3 -o
.libs/t-bswap t-bswap.o  ./.libs/libtests.a

collect2: ld returned 1 exit status
make[4]: *** [t-bswap] Error 1
make[4]: Leaving directory `/tmp/gmp-4.2.1-rc/tests'

options for configure were --prefix=/usr/local/gmp-4.2.1-rc
--enable-alloca=no --enable-fat

The problem goes away if I remove "--enable-fat" from the configure-options.

(I know, it is a little old :))
