Right now dotprod_c* does:
./generated/dotprod_c4.c:      COMPLEX_ASSIGN(conjga, REALPART (*pa), -IMAGPART
(*pa));
./generated/dotprod_c16.c:      COMPLEX_ASSIGN(conjga, REALPART (*pa),
-IMAGPART (*pa));
./generated/dotprod_c8.c:      COMPLEX_ASSIGN(conjga, REALPART (*pa), -IMAGPART
(*pa));
./generated/dotprod_c10.c:      COMPLEX_ASSIGN(conjga, REALPART (*pa),
-IMAGPART (*pa));


When it should be doing:
conjga = conj(*pa);
or
conjga = conjl(*pa);
or
conjga = conjf(*pa);

Depending on which type it is.

Or it could use the GNU extension which overrides ~ for conjugation.

conjga = ~*pa;
