Re: Fwd: Bug#208214: acx_blas should work for C and C++ as well

That's all acx_blas is supposed to check for, since the C and C++ bindings
have incompatible interfaces.  If you want to check for the C bindings,
you need to write an acx_cblas macro.

I always use the Fortran bindings, myself, even though I call them from C
(with the help of AC_F77_WRAPPERS etc) since I find that the C bindings
are often unavailable.

(The situation is different for MPI, since both C and Fortran interfaces
have been there forever and people essentially never call one from the
other.)
