Re: [Tinycc-devel] parsing 0x1e+1 as 0x1e +1

pcc outputs 0x10 0x1e too. But tcc with first patch outputs 0x10 0x1d
(as user expects)

PS: a second patch attached which allows to add space after 0x1e. It
is based on scanning expanded string of the macro in next(). and
checking some rules. For example, a patch inserts a space after
TOK_PPNUM which followed by '+' or '-'. May be this is needed only
when -E is given..
