I really don't know much about this, but, based on my quick reading of the VectorLinux site, the 64-bit version is still in beta release, and is probably not the version you are running. The bash you are using is 32-bit while you are trying to use a 64-bit version of AFNI. Try the gcc32 or xorg7 (not 64-bit) versions of AFNI instead, or you might try a different Linux distribution to run within the Windows environment.
