To work around a compiler bug? The obvious disadvantage of this is that
you won't easily find out when the bug is fixed.  There was an egcs
optimization bug on Alpha which is now fixed, but that was never taken
care of by configure.

For Linux on Sparc, I have put the fix in the spec file for the RPM,
where it remains quite visible and can be tested periodically.
