This is a completely ridiculous assertion. Do you have any
evidence to back this up? There is no reason that GCC could not intercept
Sun CC if some effort were made. SPARC is not that different from other
RISC architectures that GCC supports well. If Sun wants to protect its
compiler business, that is fine, but it is a business decision, not a

Has anyone at Sun investigated and analyzed the source of the gap
relative to a recent version of GCC? If Sun does not want to cooperate
with the Free Software community, that may be a reasonable business
decision, but at least provide the real explanation or do not say anything
instead of excuses.
