Interesting. I just did the same thing, and it still doesn't work
correctly.
Under Cygwin, this program:
#include <stdio.h>
int main(void) {
float f = 123.456;
double d = 123.456;
long double ld = 123.456;
printf("float: %d bytes, double: %d bytes, long double: %d bytes\n",
(int)sizeof (float),
(int)sizeof (double),
(int)sizeof (long double));
printf("f = %g\n", f);
printf("d = %g\n", d);
printf("ld = %Lg\n", ld);
return 0;
}
produces this (correct) output:
float: 4 bytes, double: 8 bytes, long double: 12 bytes
f = 123.456
d = 123.456
ld = 123.456
Under MinGW, installed from scratch on Windows 7 just a few minutes
ago,, with gcc 4.6.1, the same program produces this output:
float: 4 bytes, double: 8 bytes, long double: 12 bytes
f = 123.456
d = 123.456
ld = -6.41666e+264
Can you try this program on your system?
