I must admit that I am a bit clueless here. Google showed similar problems
in various projects, but I haven't found a cure or the exact reason for this.
Maybe we steal too many SPARC registers? But why does it only happen for this
module? Perhaps Sun has still the bad habit of deviating from the standard
and uses macros instead of function calls for some OpenGL entry points, see
e.g.:

    ftp://docs-pdf.sun.com/805-4445-12/805-4445-12.pdf

Christian: Can you try to hack the Makefile to add -DSUN_OGL_NO_VERTEX_MACROS
to gcc invocations, please? Another test might be using Mesa instead of Sun's
OpenGL.

Cheers,
