Actually, this would work by first decoupling clucene to use a separate type clucene_float_t and then defining that as float_t or double on s390x: Something like: #ifdef __s390x__ #define HAVE_SPECIAL_CLUCENE_FLOAT_T #define SPECIAL_CLUCENE_FLOAT_T double #endif #ifdef HAVE_SPECIAL_CLUCENE_FLOAT_T typedef SPECIAL_CLUCENE_FLOAT_T clucene_float_t; #else typedef float_t clucene_float_t; #endif The required changes in the rest of the code are trivial (i.e., search and replace) -- updated patch attac...

Indeed, this patch is just plainly broken.

Patch: Clamp float_t to double on s390 to keep ABI stable
