5accccd051 Fix problem introduced in yesterday's commit that broke both signed and 
unsigned character machines. So that people don't have to reverse engineer
this again:
	mksyntax detects if characters are signed or not and builts a syntax
	table that has a base of 129 for signed characters or 1 for unsigned
	characters. This is so the largest negative signed char [-128] + the
	base == 1. 0 is special and means end of file in both cases. PEOF
	is -1 for the unsigned character case and -129 for the signed
	character case, so that syntax[PEOF + base] == syntax[0] == CEOF
	So PEOF has to be -1, but it is explicitly compared with
	unsigned characters on machines where characters are unsigned.
	The quick fix is to define UPEOF the (unsigned char) version of PEOF
	and use that. A better fix is to always use unsigned characters
	when referencing symbol table entries, but that would require
	extensive changes to the shell. So to summarize

	syntax[0] == CEOF, base + PEOF == 0

		unsigned	signed
	base	1		129
	PEOF	-1		-129
