gcc43 install error

[mfaridi]

I want install gcc43 , but I see this error

Making GCC 4.3.4.20090705 for FreeBSD 7.0  target=i386-portbld-freebsd7.0
You need to increase the datasize limit to at least 700000 (and set
kern.maxdsiz="734003200" in /boot/loader.conf) to build with Java
support.
*** Error code 1

so I put

kern.maxdsiz="734003200"

in

/boot/loader.conf

. but still I see that error , I do not want reboot my system because it work for another project

The items specified in /boot/loader.conf are done when the system boots.

Use $ sysctl kern.maxdsiz=734003200 to have immediate effect.
