Printing the flags is not intended for the casual user.  So, I'd like to 
keep consistent with C-level names and the names that are printed.

CONTIGUOUS is the old name Numeric used.  It always meant C-CONTIGUOUS 
and so that meaning is preserved.  FORTRAN is the new one flag and it 
means FORTRAN CONTIGUOUS.

So, you want something like?

#define NPY_C_CONTIGUOUS NPY_CONTIGUOUS
#define NPY_F_CONTIGUOUS NPY_FORTRAN

and to have C_CONTIGUOUS and F_CONTIGUOUS print for the flags description?

I'm not opposed to it, but I don't really see the need.  It's just a 
semantic question.  Given the history of CONTIGUOUS in Numeric I thought 
it was clear that CONTIGUOUS always meant C-contiguous.
