It occurs to me that this depends on ratpoints, which has some issues
compiling with earlier versions of gcc. What version are you using?
GCC 4.2.1 on a SPARC is showing a slightly more helpful error message. See

This will come as no great surprise, since the setups are not very different
(same gcc version, though different versions of the SPARC processor), but this
failed on my own Sun Blade 2000 too. So it seems Fedora Linux and Solaris 10 on
SPARC are affected by this.
However, there is something a bit odd. In the post Nathann Cohen on his Fedora
system, we can see that the final compile line ends in a '-w' which is supposed
to suppress all warnings (much to my annoyance). The same '-w' is seen on 't2',
which has a SPARC processor.
For reasons unknown, the '-w' option is *not* included on my build on the Sun
Blade 2000, so the warnings are displayed.
Why an option to suppress warnings is seed on Fedora and one SPARC machine, but
not on the build of another SPARC machine is anyones guess!
