Matthijs Kooijman 4cf21dcdd1 Don't store peeked characters in a char variable ... peekNextDigit() returns an int, so it can return -1 in addition to all 256 possible bytes. By putting the result in a signe char, all bytes over 128 will be interpreted as "no bytes available". Furthermore, it seems that on SAM "char" is unsigned by default, causing the "if (c < 0)" line a bit further down to always be false. Using an int is more appropriate. A different fix for this issue was suggested in #1399. This fix helps towards #1728.		2014-02-19 16:09:30 +01:00
