These are the patches to Nachos required for g++ version 2.6 and 
above.  The first is because g++ has started enforcing the use
of lower case true and false as keywords.  The second is
because g++ continually redefines the UNIX system call interface!

In utility.h, replace:

typedef enum { FALSE = 0, TRUE = 1 } bool;   // Boolean values.

with:

// typedef enum { FALSE = 0, TRUE = 1 } bool;   // Boolean values.

#define TRUE  true
#define FALSE  false

In sysdep.cc, replace:

#ifdef HOST_SNAKE
// int creat(char *name, unsigned short mode);
// int open(char *name, int flags, ...);
#else
int creat(char *name, int mode);
int open(char *name, int flags, int mode);

with

#ifdef HOST_SNAKE
// int creat(char *name, unsigned short mode);
// int open(char *name, int flags, ...);
#else
// int creat(char *name, int mode);
// int open(char *name, int flags, int mode);
