fold-const.c (fold): Use the original type conversion tree code rather than call fold_convert...
* fold-const.c (fold) <NOP_EXPR>: Use the original type conversion
tree code rather than call fold_convert, which doesn't specify a
default floating point to integer conversion.
* gcc.c-torture/compile/20040209-1.c: New test case.
