From an article on Sunsoft's plans to publish Solaris (SunOS) for general Intel-based machines which appeared in the September 5 edition of the San Jose Mercury News:

While programs written for Sun machines won't run unmodified on Intel-based computers, Sun said the two packages will be completely compatible and that software companies can convert a program from one system to the other through a fairly straightforward and automated process known as "recompiling."
