syntax error: [string "return 42"]:1: malformed number near '42ÿ'

Ah, ÿ is 0xFF. So, somehow -1 is getting mapped into 0xFF.
It seems to be a faulty isdigit, which is mapping -1 to 0xFF *and*
thinking 0xFF is a digit! Try using your own isdigit...

Where does that -1 come from? I replaced isdigit() in read_numeral by
the following, no change:

static int
isadigit(char c)
if (c >= '0' && c <= '9')
return 1;
return 0;

If you want to trace this, the place to start is read_numeral in llex.c.

isalnum(-1) indeed returns != 0 on Windows Mobile. Looks like a signed/unsigned char, Unicode or related problem to me.
