I compiled fpc from the sources from the svn repository today, but the 
results are almost the same as I posted yesterday (I marked with ** 
where the results have changed):

Test1:
 ** fpc (standard MM):  3.0 sec - factor = 1.30
 fpc (FastMM4):  2.9 sec - factor = 1.30
 delphi (standard MM): 3.1 sec - factor = 1.34
 delphi (FastMM4): 2.3 sec - factor = 1

Test2:
 fpc (standard MM): 2.8  sec - factor =  1.47  
 ** fpc (FastMM4):  2.1 sec - factor = 1.10
 delphi (standard MM): 2.9 sec - factor = 1.52
 delphi (FastMM4): 1.9 sec - factor = 1

Test3:
 fpc (standard MM):  2.5 sec - factor = 1,19
 fpc (FastMM4):  2.1 sec - factor = 1
 delphi (standard MM): 3.4 sec - factor = 1.61
 delphi (FastMM4): 2.1 sec - factor = 1
