  If you say so.  That library contains the entire vxworks OS, not just
the BSP you know ?  You really don't want any of it ?  Then yes, you
should build a new compiler from the source.

  Yeah, that would work.  You'd need to build the code using newlib
instead of the vxworks header files.  And you'd want powerpc-eabi,
definitely.  It seems powerpc-elf actually means SysV!
