Aka 'intmax_t', as recommended by newer standards.
For example
if (-0x80000000 < 0) is false,
but
#if (-0x80000000 < 0) is true
because in C, 0x80000000 is an unsigned int, Whereas in
a preprocessor expression, it is a signed long long, even
without LL suffix.
- remove TOK_NOSUBST, mark the token itself instead
- get_tok_str(); mask out SYM_FIELD & update uses
- next(): optimize (~5% faster with tcc -E)
- tok_flags: remove some redundancy
- parse_define(): do not remove spaces around '##' and after '#'
and mark macros with '##' as MACRO_JOIN to avoid unnecessary
call to macro_twosharps(mstr):
- next_nomacro(): removed, next_nomacro1(): renamed to next_nomacro()
- next_argstream(): cleanup & new function peek_file()
- macro_subst_tok(): handle special macros (__DATE__ etc.)
like normal macros if they are #defined
- -DPP_DEBUG : more structured output
- pp_error(): better preprocessor expression error message
- tcctok.h: sort basic keywords (somehow)
- testspp/Makefile: generate .expect with 'make testspp.##+'
- tcc.c: tcc -E -o file : put unixy LFs also on windows
That means: we do not macro-expand the argument of 'defined'
Also: store the last token position into the TokenString
structure in order to get rid of the tok_last function.
