warning in make speed

[Paul Zimmermann]

       Hi,

with gmp-4.3.1, on a Core 2 (but I doubt it makes any difference) with
GCC 4.4.2, I get a warning in "make speed":

tarte% cd /tmp/gmp-4.3.1/tune/
tarte% make speed
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../tests    -O2 -pedantic -m64 -mtune=core2 -c speed.c
/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../tests    -O2 -pedantic -m64 -mtune=core2 -c -o common.lo common.c
 gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../tests -O2 -pedantic -m64 -mtune=core2 -c common.c -o common.o
common.c:1211:1: warning: invoking macro SPEED_ROUTINE_MPN_GCD_1_CALL argument 1: empty macro arguments are undefined in ISO C90 and ISO C++98
