Compile time floating point exception

[Jonathan Blanchard]

I had gmp compile and check correctly on core2-pc-solaris2.11 using
sun studio 12. With the following script :

#!/bin/bash

export CC="cc"
export CXX="CC"
export F77="f95"

export LDFLAGS="-L/opt/SunStudioExpress/lib/"
export LD_OPTIONS=$LDFLAGS
export PATH=/opt/SunStudioExpress/bin:$PATH

export CFLAGS="-xO5 -m64"

./gmp-4.2.4/configure --prefix=$HOME/local/gmpss
LDFLAGS="-L/opt/SunStudioExpress/lib/" --build=core2-pc-solaris2.11

if [ "$?" -eq "0" ]
	then
	make -j 4

	if [ "$?" -eq "0" ]
		then
		make check
	fi

fi
