So these definitions are currently not being used at all? |

Do we want a test for these functions? |

Because the numpy functions are in C, I think that f2c_blas and lapack_lite are always paired. Multiarray does use the dot functions, but from CBLAS, with its own fallback C implementations. How did you manage to call the f2c_blas functions? |

LGTM, I don't think there is a problem ... |

Yeah, let's merge this, I don't see a problem. Thanks Eric. |

F2C does not support complex return values, and puts these as the first argument.
This can be checked by looking at
numpy\linalg\lapack_lite\f2c_blas.c.It's not clear to me if these prototypes are exclusively for lapack_lite, or if they also need to match the system lapack (in which case the
f2c_...in the typenames is very misleading).This fixed a segfault on my machine (using lapack_lite) when trying to call these functions in the C code.
