With 4.3.3 the following line doesn't compile:

#include <float.h>

static double minTime = DBL_MAX;

error: initializer element is not constant.

Is that a new C rules ?  In float.h if STDC_VERSION is <= 199901 DBL_MAX would be equal to 0xf.ffffffffffff8p+1020, but 
instead it's _CSTD _Dbl._Dmax._Double
