It's a shame it can't be configured, but I understand your reasons.

Unless I am mistaken, this problem is only seen with gcc. In which case, the 
removal of the optimiser can be condition on __GNUC__ being defined.

The leaves only one other package (R) in Sage that is not building properly 
64-bit on Solaris. R is less critical, as a failure of R to build only affects 
that one package - not the whole of Sage. Whereas ECL was causing more serious 
problems. Since R is not linked, but only called via a pexpect interface, it is 
not as serious.

If Juanjo could point out the bit of code that actually causes the problem, I'd 
be interested. I'd like to get this submitted as a bug to gcc, as the Sun 
compiler can I believe work around this issue, moving the relevant code to a 
section which is read-write, and not read-only.
