ISTR that it used to be (at least) with DOS that the interpreter/shell 
(ie, command.com) had special handlers for .com and .exe and that you 
couldn't execute a program with.  That said, I do know that the exec... 
and spawn... C functions could launch any file as an executable (used to 
do this myself, actually - replacing a login.exe file with a custom-
written wrapper that exec'ed a login.nov executable).
