No.  But they don't really support their products all that well
under Windows either.

I've or heard about others using Linux as a 
development host. WRS uses either GNU or Diablo compilers.  We are
using GNU gcc 2.96.x.  Tornado is weak and expensive.  Support is weak. 
We have a requirement to build a loader. The incentive to stay with 
Windows/Tornado is dwindling.

I think one has to build one's own toolchain (cross compiler/linker/
loader).  I can't think of a reason why vxworks objects would not
link/locate successfully to objects compiled with the same compiler
running under linux.  Cross compiling to PPC using gcc2.96 under
XP should yield the smae objects as cross compiling the same source
to PPC using the same compiler under Linux.

A fellow contractor told me about a university that figured it out
to reduce maintenance costs, but she lost the web link.
