I have a license for a HiTech compiler. I don't remember when exactly I
bought it, but it was around ten years ago. And I expect to get still a few
years out of it before it becomes obsolete. (Of course, in the meantime I
also invested a few years of maintenance contract into the product.)

IMO, with embedded compilers, it mainly depends on the success of the chip
families it supports. If both the chip family and the compiler manufacturer
are reasonably successful, the compilers don't tend to become obsolete very
quickly.
