bug#9960: Compiling Emacs trunk with MSVC

[Fabrice Popineau]

Can you show how the values of the following variables change as you
step through this fragment in read1 and inside read_escape it calls?

 read_from_string_index
 read_from_string_index_byte
 read_from_string_limit

c 0x00000043 int

read_from_string_index 0x00000004 int

read_from_string_index_byte 0x00000004 int

read_from_string_limit 0x00000008 int

case 'C':

  c = READCHAR;

c 0x0000002d int

read_from_string_index 0x00000005 int

read_from_string_index_byte 0x00000005 int

read_from_string_limit 0x00000008 int

      if (c != '-')

error ("Invalid escape character syntax");

    case '^':

      c = READCHAR;

c 0x00000030 int

read_from_string_index 0x00000006 int

read_from_string_index_byte 0x00000006 int

read_from_string_limit 0x00000008 int

return c | ctrl_modifier;

back to read1:

modifiers = c & CHAR_MODIFIER_MASK;

c &= ~CHAR_MODIFIER_MASK;

if (CHAR_BYTE8_P (c))

 c = CHAR_TO_BYTE8 (c);

c |= modifiers;

next_char = READCHAR;

c 0x04000030 int

next_char 0x00000030 int

read_from_string_index 0x00000007 int

read_from_string_index_byte 0x00000007 int

read_from_string_limit 0x00000008 int

ok = (next_char <= 040

     || (next_char < 0200

 && strchr ("\"';()[]#?`,.", next_char) != NULL));

                ok = 0 => error

Hope you can decipher this.
