Provide a scripts/mencc, scripts/menld and scripts/menuet.lds for your
compiler.

To compile with other compilers than gcc provide a file analagous to
<menuet/gcc/syscall.h> for the new compiler. This file must provide the
following functions:

  long do_menuet_syscall_ret(long a)
	place a in EAX, exec int 0x40, return EAX.
  long do_menuet_syscall_ret_b(long a, long b)
	place a in EAX, b in EBX, exec int 0x40, return EAX.
  long do_menuet_syscall_ret_bc(long a, long b, long c);
	place a in EAX, b in EBX, c in ECX, exec int 0x40, return EAX.
  long do_menuet_syscall_ret_bcd(long a, long b, long c, long d)
	place a in EAX, b in EBX, c in ECX, d in EDX, exec int 0x40,
	return EAX.
  long do_menuet_syscall_ret_bcdS(long a, long b, long c, long d, long S);
	place a in EAX, b in EBX, c in ECX, d in EDX, S in ESI,
	exec int 0x40, return EAX.
  long do_menuet_syscall_ret_bcdSD(long a, long b, long c, long d,
	long S, long D);
	place a in EAX, b in EBX, c in ECX, d in EDX, S in ESI, D in
	EDI, exec int 0x40, return EAX.
