[fpc-devel] FPC trunk compiler slower than 3.0.4

I observe that FPC trunk compiler is about 65-70% (factor 1.65-1.7) 
slower than FPC 3.0.4 compiler.

E.g. building Lazarus IDE takes on my machine:
1:00 with FPC 3.0.4
1:40 with FPC trunk

Do you observe the same? Any hints why? Is anybody worried about the 
speed? Is anybody working on the speed issues? The compile time increase 
is huge.

I seem to have the same fpc.cfg and FPC/Lazarus build options.
