no CreateProcess will no allow running 16 bit execs (while WinExec16
does)

a way to do it is to replace the is32 boolean in most functions with a
function pointer to the actual process creation implementation

it's signature would be HINSTANCE (*fn)(char *lpCmd, LPSHELLEXECUTEINFOA
sei, BOOL shWait) and would be passed to ShellExecuteExA32
from a 32 bit function, code would the 32 bit part of SHELL_ExecuteA
from a 16 bit function, code would the 16 bit part of SHELL_ExecuteA
(this part should all be moved to 16 bit code)
