gcc64 use flag

Hi all,
   This morning I was looking at doing some updates and
noticed the
gcc64 use flag on linex-headers. Although this is an AMD64
machine
I've not been using this flag and am wondering if I should
be? What
exactly does it do?

[ebuild     U ] sys-kernel/linux-headers-2.6.21 [2.6.17-r2]
USE="(-gcc64%)" 4,287 kB


lightning ~ # emerge -pv
=sys-kernel/linux-headers-2.6.17-r2

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] sys-kernel/linux-headers-2.6.17-r2 
USE="(-gcc64)" 0 kB

Thanks,
Mark

The flag seems to be disabled so it seems you shouldn't be
using it. I
am not sure what it exactly does, but the Gentoo use flag
page says "Use
64-bit kernel compiler" for gcc64. I'd assume since
it's unchangeable at
this point it doesn't matter anymore.

An old friend said:

The USE flag is only effective on ppc64 and sparc where the
kernel sometimes 
is the only code that is compiled 64bit and therefore a
seperate, much 
smaller version of gcc is used to build the kernel. The flag
should in fact 
be masked everywhere except for those profiles, which is
what bug 144535 [1] 
deals with.
