I'm wondering if we should also add a configure-time compile test in float_h.m4, which does the sanity check of this untested snippet: AC_CHECK_SIZEOF([double]) AC_CHECK_SIZEOF([long double]) AC_COMPUTE_INT([variable], [(SIZEOF_DOUBLE == SIZEOF_LONG_DOUBLE) == (DBL_MANT_DIG == LDBL_MANT_DIG)], [<float.h>]) Then we could make float.in.h always be replaced if the sanity check fails, and additionally make it robust enough to #error out (or equivalent) for platforms where we have not ported the correct characteristics, rather than the current scenario of silently doing nothing about the bad <float.h>. - -- Don't work too hard, make some time for fun as well!
