HAVE(FLOAT_H) is meant to guard <float.h> includes. As of now the number of _unguarded_ <float.h> includes is 13; there is only 2 locations where float.h is guarded. Based on these numbers it seems clear that neither JavaScriptCore nor WebCore would not build without float.h available. All build would have to define HAVE(FLOAT_H), which is not the case today - and this sometimes leads to build inconsistencies (e.g. http://trac.webkit.org/changeset/51170). I would proposed to remove the HAVE(FLOAT_H) - as this seems to be a hard dependency for all WebKit components. Patch will follow.
