RE: [Vxl-maintainers] MSVC 6 problem with vnl_matrix_fixed * vnl_matrix_fixed

[Andrew F. <aw...@ro...>]

I am currently running through OXL and fixing some of these
issues.  OXL uses the fixed-size things quite heavily,
so it is stretching the implementation.  In some cases, the
splitting of *_fixed and * has revealed some design 
issues in OXL, in others there are many fixes which will
run and work fine, but there may be gotchas...

Who else is making OXL compile?
