gcc on Sparc Solaris 8

  For example: XAllocColorCells is not working.


A very basic Xlib function is not working ??  Really ??

This ?

      Status XAllocColorCells(display, colormap, contig,
      plane_masks_return, nplanes,
                                pixels_return, npixels)
            Display *display;
            Colormap colormap;
            Bool contig;
            unsigned long plane_masks_return[];
            unsigned int nplanes;
            unsigned long pixels_return[];
            unsigned int npixels;


As for floating point numbers.

Floating point numbers exist in binary with a trivial format of a sign
bit and then some bits for an exponent and then lastly a string of bits
to represent the significand.  The significand ( or mantissa ) data also
has an implied leading bit of "1" for normal numbers.  How you choose to
print them out is entirely your business.

The Oracle Solaris 12.6 Developer tools are a free download and I do
suggest you look at them. I am fairly sure that support for Solaris in
gcc has been dropped as of last year. At least for Solaris 10. Sadly I 
have never seen Solaris 11 in the wild. Maybe that works and maybe it 
does not. Have you considered simply moving over to FreeBSD or even dare 
I say it Linux?  I have heard in various places that this "Linux" thing 
works quite well and I have even seen it running neatly.  Could be worth
a look. :) Just don't go lookng too closely for POSIX compliance or even
cross platform clean compiles.
