I#m not really sure it is the evaluation order, but at the moment 
this
is my best guess.
I had to loosen the relatice error bounds for two test in
rtest_gamma.mac from 5.9b-24 to 7.8b-24 and from 6.6b-25 to 
8.3b-25
where fpprec was set to 24.
The relevant change is in rpart.lisp in the function
risplit-expt-sqrt-pow where the macros (1//2) and (half) were 
changed to
the variable 1//2.
