I'm trying to compile libc using gcc 3.03 and get:
e:/djgpp/bin/make.exe -C ansi/stdio
gcc ... -c doprnt.c
cc1.exe: warnings being treated as errors
doprnt.c: In function `_doprnt':
doprnt.c:303: warning: signed and unsigned type in conditional expression
doprnt.c:347: warning: signed and unsigned type in conditional expression
doprnt.c:354: warning: signed and unsigned type in conditional expression
make.exe[3]: *** [doprnt.o] Error 1
make.exe[2]: *** [all_subs] Error 2
make.exe[1]: *** [all] Error 2
make.exe: *** [subs] Error 2


Macro ARG:

#define ARG(basetype) _ulonglong = \
                flags&LONGDBL ? va_arg(argp, long long basetype) : \
                flags&LONGINT ? va_arg(argp, long basetype) : \
                flags&SHORTINT ? (short basetype)va_arg(argp, int) : \
                va_arg(argp, int)


Lines around 303:
    case 'O':
      flags |= LONGINT;
      /*FALLTHROUGH*/
    case 'o':
      ARG(unsigned); /* This is line 303. */
      base = 8;
      goto nosign;
    case 'p':

Lines around 347 and 354:
    case 'U':
      flags |= LONGINT;
      /*FALLTHROUGH*/
    case 'u':
      ARG(unsigned); /* Line 347. */
      base = 10;
      goto nosign;
    case 'X':
      digs = "0123456789ABCDEF";
      /* FALLTHROUGH */
    case 'x':
      ARG(unsigned); /* Line 354. */
      base = 16;
      /* leading 0x/X only if non-zero */
      if (flags & ALT && _ulonglong != 0)
        flags |= HEXPREFIX;


I'm not sure what I should do to solve this.


Right,
