Tested, need to include <winbase.h> (and <windows.h>).
gcc juste produce a warning with VirtualProtect:
/home/ronald/Prog/Win32/combo/qemu/exec.c: Dans la fonction « page_init »:
/home/ronald/Prog/Win32/combo/qemu/exec.c:155: AVERTISSEMENT: passage de
arg 1 de « VirtualProtect » transforme en pointeur un entier sans
transtypage

aproximative translation: in function page_init passing arg1 of
VirtualProtect is making pointer from integer without a cast.

Note: with **VirtualProtect or *VirtualProtect make is aborting, I have
used VirtualProtect.
