Not sure. Adding flag -fno-inline to the compile line:

$  time ~/gcc/results.265139.release/bin/gcc -w -I ../trunk/runtime -O2 -c
-fno-inline destDir/testFile.8458.c 

real    0m47.647s
user    0m45.990s
sys     0m0.473s

So it seems that if the inline is switched off, compile time reduces a lot
(92%).

$ fgrep -c inline destDir/testFile.8458.c
0
$

Doesn't make much sense to me.
