Perhpas more a philisophical question, but do we really need configure tests for .h file defines. I just saw masts commit of testing for the existance of FIELD_TYPE_BIT and then doing

#ifdef HAVE_FIELD_TYPE_BIT case FIELD_TYPE_BIT: #else case 16: #endif

wouldn't no configure test and a

#ifndef FIELD_TYPE_BIT #define FIELD_TYPE_BIT 16 #endif

had had the same result?
