#4776 is definitely a separate issue. #4007 could be related similar f2c ABI issues, but I don't think so. The difference between the gfotran and g77/f2c ABIs, to my knowledge, is that (1) fortran REAL (single precision floating point) return values are actually returned as a c double, not a c flo

Yeah, that's definitely not the right signature for sdot when linked against the Accelerate framework. But what's the purpose of those wrappers in _umath_linalg? The one for sdot, for example, doesn't appear to be used internally, and it isn't available from the python side. While scipy has all of
