This is because you have 'soft-float' defined somewhere and are not loading
the floating point emulation libraries that come with vxWorks.  I don't
know *how* you are supposed to load them... I don't use that stuff, but
I suspect that if you build vxWorks for soft-float, they are built in.

I also suspect that you have a board with floating point on it... are loading
the vxWorks w/o soft-float (as you should for that board) and are just building
EPICS wrong (for a soft-float environment.)

Not that I am aware of.

>Q: Is this a bug?

Nope.  It is a feature ;-)
