Net version 1.1.0: gcc 2.95.2-2 compiler bug


In porting some astronomical data handling software from linux/unix to
Cygwin (the latest nework release, 1.1.0 I believe), I discovered an
error in how gcc 2.95.2-2 generates output of a floating or double
variable set to 0.0 when formatted with a %E format.  I didn't get any
hits on this problem in the FAQ or mail lists.  The following little
test program illustrates the problem:


main()
{
	float value = 0.0;
	double dvalue = 0.0;
	printf("%11.0f %15.6f %13.5E\n",value,value,value);
	printf("%11.0f %15.6f %21.14E\n",dvalue,dvalue,dvalue);
	dvalue = value = 3.0;
	printf("%11.0f %15.6f %13.5E\n",value,value,value);
	printf("%11.0f %15.6f %21.14E\n",dvalue,dvalue,dvalue);
}
	        
Under linux/unix, this little program produces the following
output:

          0        0.000000   0.00000E+00
          0        0.000000  0.00000000000000E+00
          3        3.000000   3.00000E+00
          3        3.000000  3.00000000000000E+00

But the following is produced by the Cygwin gcc 2.95.2-2:

	  0        0.000000   0.
          0        0.000000  0.
          3        3.000000   3.00000E+00
          3        3.000000  3.00000000000000E+00

When the output is sent to the terminal screen, the results for 0.0 with
the E format come out as 0.  followed by some "strange" characters and
then E+00.  Saving stdout to a file and then moving from Cygwin to linux,
I find there are a bunch of control characters after the leading 0.  and
preceeding the E+00. 

Sorry, I don't know enough about compilers to even take a wack a solving
this problem, but would very much appreciate a patch for the sources
or a working binary with the patch incorporated if someone could kindly
generate one. 

Thanks,
