For those of you who are members of the 'Compiler of the Month Club'

I just got Datalight's Optimum C - hence the tests.

Test Conditions

Microsoft C 4.0
Datalight Optimum C 3.05

All compilers set for small data, small code, .exe format, no 'EXEPACK.'
Maximum optimization selected for all compilers.

Testing done on an IBM AT (bad old model) with 8 MHZ clock.
