[Bug c/39037] New: FLOAT_CONST_DECIMAL64 pragma not supported

[tydeman at tybor dot com]

Using gcc 4.3.2-7 on Intel Pentium 4 running Linux Fedora Core 10 with
-std=gnu99

/* DFP TR 24732 == WG14 / N1312 */
#define __STDC_WANT_DEC_FP__ /* Tell implementation that we want Decimal FP */
#pragma STDC FLOAT_CONST_DECIMAL64 ON /* unsuffixed => Decimal (not Binary) */

_Decimal64 d10 = 1.0DD / 3.0 ;     /* 3.0 should be treated as 3.0DD */

gets:

test7.c:5: warning: ISO C does not support decimal floating point
test7.c:5:18: warning: decimal float constants are a GCC extension
test7.c:5: error: can't mix operands of decimal float and other float types

NOTE:  This pragma is new with WG14 N1312 version of Decimal Floating Point
Technical Report (it replaced Translation Time Data Type (TTDT)).
