Description Fred J. Tydeman 2009-01-30 01:05:46 UTC 
Using gcc 4.3.2-7 on Intel Pentium running Linux Fedora Core 10
with -std=gnu99 of

/* DFP TR 24732 == WG14 / N1176, N1312 */
#define __STDC_WANT_DEC_FP__ /* Tell implementation that we want Decimal FP */
#include <float.h>	/* DEC_EVAL_METHOD */

#ifndef DEC_EVAL_METHOD
#error Missing DEC_EVAL_METHOD
#endif

int main(void){
    return 0;
}

gets:

#undef DEC_EVAL_METHOD
#define DEC_EVAL_METHOD __DEC_EVAL_METHOD__


It is there on the trunk.
