I've used Kurt's second inline patch on GCC 3.1 CVS and run the
SPECint2000 programm 252.eon with it.
Without Kurt's patch:
$ time make bootstrap
real 39m54.271s
user 36m28.650s
sys 1m46.330s
$ time runspec --action=build -l 252.eon
real 14m4.484s
user 13m19.120s
sys 0m20.800s
Runtime:

252.eon 1300 459 283
252.eon 1300 458 284
252.eon 1300 459 283*
With Kurt's patch:
$ time make bootstrap
real 40m3.185s
user 36m24.260s
sys 1m45.810s
$ time runspec --action=build -l 252.eon
real 14m2.593s
user 13m6.430s
sys 0m21.010s
Runtime:
252.eon 1300 437 297
252.eon 1300 437 297*
252.eon 1300 437 297
The compile time shows no difference but the execution is 5% faster
(459s -> 437 s).
