printf and floating point emulation



I have a program that hangs when trying to format and print something like this:


void
func (float f)
{
   printf ("%.2f\n", f);
}

I don't have an FPU builtin hardware.
The CPPFLAGS and LDFLAGS include the following options:

-msoft-float -mno-fp-ret-in-387 -mno-fancy-math-387

I disabled the FPU support (macro CYGHWR_HAL_I386_FPU) and I enabled CYGSEM_LIBC_STDIO_PRINTF_FLOATING_POINT and CYGSEM_LIBC_STDIO_SCANF_FLOATING_POINT macros.

I'm running ecos-2.0 (the last version available in CVS).

Please, I cannot realize what I'm omiting.. Any idea?
