I am on a x86 (not x86_64) host, running OpenSuse 10.3,
including :

	gcc version 4.2.1 (SUSE Linux)

I built the clfs system the day I wrote the mail, using the latest svn version
of clfs-development and the latest jhalfs-svn version (with a fix to jhalfs
to use the linux tarball for linux-headers).

Could the x86 vs x86_64 make a difference ?

Best regards
