Very interesting.

I'm wondering whether -- in the spirit of competition -- to have a go at
including a binding in Ada 2005 Math extensions, even though it's
somewhat outside the scope as I'd seen it.

I can see a problem writing a general binding for code like this
(umf_solve.h):

   GLOBAL Int UMF_solve
   (
       Int sys,
       const Int Ap [ ],
       const Int Ai [ ],
       const double Ax [ ],
       double Xx [ ],
       const double Bx [ ],
   #ifdef COMPLEX
       const double Az [ ],
       double Xz [ ],
       const double Bz [ ],
   #endif
       NumericType *Numeric,
       Int irstep,
       double Info [UMFPACK_INFO],
       Int Pattern [ ],
       double SolveWork [ ]
   ) ;
