I'm using LIBTIFF, Version 3.2 BETA on a Sun Sparc Workstation running SunOS 4.1.3

Compiling the library using the Sun cc compiler I had some problems with setting TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION, while using the GNU compiler everything works.

The problem is in TIFFWriteRational(). Look at this simple program (similar to TIFFWriteRational()):

main()
{
        a(200.0);
}

a(x)
        float x;
{
        b(&x);
}

b(x)
        float *x;
{
        printf("%f",*x);
}

If you compile it using the Sun cc compiler the output will be:

        3.640625
while if you compile it using the GNU compiler the output is:
        200.000000

Is this a known bug of the Sun cc compiler?
