Parrot_Exec_OS_Command interface ?

[François PERRAD]

When I analyse the failure of t/pmc/sys.t with MinGW32,
I see that this script generates a command depending of the OS
        on MSWin32, cmd = ".\parrot temp.imc"
        on *nix, cmd = "./parrot temp.imc"

(So with MinGw, the generation of Makefile needs /, and the execution needs \)

The bug can be fixed in ConfigureLand or in Parrot_Exec_OS_Command function.
And the dilemma is :
        the interface of Parrot_Exec_OS_Command is OS native command as now,
        or is OS independent, like "open dirname/filename"
