I am running a uVax II with Ultrix 2.0, gcc-1.35.  I have seen reports
for this bug before, and I am wondering if there is a simple fix.

The following program generates the error noted below it:

-----------------------

main()
{
  float	x;
  x=1;
  printf ("%g\n",x);
}

gccbug.c:4: Magnitude of constant too large for 'float'

--------------------------------

The same behaviour occurs if line 4 is changed to x=1.0.  This can be
circumvented if I say:
  int y = 1;
  x = y;

But what happens when I want x=1.5 ?
