Yes. The programs were compiled unmodified with Digital Mars compiler dmd.0.111.win32 and gdc-GCC3.4.4 20050121-prerelease.cygwin both compiles and resulting executabls ran under WinXP.PRO.servicepack2.
The dmd.win32-compile and the gdc.cygwin.win32.compile using the dmd script used the flags "-O -release -inline".
The programs compiled are the ackermann program from D-Stress benchmarks, the dhrystone program from the examples coming with dmd and my adaption of the whetstone benchamrk to D, for which I do not know, whether I am allowed to publish it.
