Try

http://www.math.purdue.edu/~lucier/_t-c-1.i.gz

I get

popov-1089% /export/u10/egcs-profile/lib/gcc-lib/alphaev6-unknown-linux-gnu/2.96/cc1 -O1 -mcpu=ev6 -fno-math-errno -mieee _t-c-1.i
...
 TOTAL                 :  31.78             0.36            32.13

BTW, with the introduction of libgcc1, I can no longer

make -j bootstrap

on my Linux box---I run out of processes with the standard value of
NR_TASKS=512!  I install a new kernel tomorrow with NR_TASKS=4096.
