1b57560502 nocode, noreturn
A more automatic approach to code suppression (aka. nocode_wanted)

The simple rules are:
- Clear 'nocode_wanted' at (im/explicit) label IF it was used
- Set 'nocode_wanted' after unconditional jumps

Also in order to test this then I did add the "function might
return no value" warning, and then to make that work again I
did add the __attribute__((noreturn)).

Also moved the look ahead label check into the type parser
to gain a little speed.

47722a8c2e fix windows errors uncovered by the inline patch
By always instantiating extern inlines, the patch has discovered
2 assembly errors, which were fixed in the original mingw64 in 2009.

This fixes those errors.

Additionally it changes __CRT_INLINE in win32/include/_mingw.h
from `extern __inline__` to `static __inline__`.

__CRT_INLINE is used exclusively in header files and as such
it should not create externally visible instantiations like a `extern
inline` would (as per the C standard).

    int __stdcall func(char buf[10]) is _func@4 (was _func@12)
- tccgen.c: fix static variables with nocode/nodata_wanted
    see tests2/96_nodata_wanted.c

7acf9aa862 final adjustments for release
- configure/Makefiles: minor adjustments

- build-tcc.bat: add -static to gcc options
  (avoids libgcc_s*.dll dependency with some mingw versions)

- tccpe.c/tcctools.c: eliminate MAX_PATH
  (not available for cross compilers)

- tccasm.c: use uint64_t/strtoull in unary()
  (unsigned long sometimes is only uint32_t, as always on windows)

- tccgen.c: Revert (f077d16c) "tccgen: gen_cast: cast FLOAT to DOUBLE"
  Was a rather experimental, tentative commit, not really necessary
  and somewhat ugly too.

- cleanup recent osx support:
  - Makefile/libtcc.c: cleanup copy&paste code
  - tccpp.c: restore deleted function

5f33d313c8 tcc: re-enable correct option -r support
Forgot about it.  It allows to compile several
sources (and other .o's) to one single .o file;

    tcc -r -o all.o f1.c f2.c f3.S o4.o ...

Also:
- option -fold-struct-init-code removed, no effect anymore
- (tcc_)set_environment() moved to tcc.c
- win32/lib/(win)crt1 minor fix & add dependency
- debug line output for asm (tcc -c -g xxx.S) enabled
- configure/Makefiles: x86-64 -> x86_64 changes
- README: cleanup

8637c1d0ad Remove misc. files
- from win32/include/winapi: various .h

  The winapi header set cannot be complete no matter what.  So
  lets have just the minimal set necessary to compile the examples.

- remove CMake support (hard to keep up to date)
- some other files

Also, drop useless changes in win32/lib/(win)crt1.c

as _alloca and later changed to alloca. Use it instead.

9d33388b29 win: libm: add implementation for round/fmin/fmax and variants
round and fmin/fmax are relatively commonly used functions but were not
implemented anywhere in the tcc Windows distribution package. Newer mingw(64)
math.h stil doesn't include these implementations.

Add C implementations for these functions and place it as inline functions at
win32/include/tcc/tcc_libm.h - which is already included from math.h .

The code is mostly taken from musl-libc rs-1.0 (MIT) [*],

musl-libc: http://git.musl-libc.org/cgit/musl/tree/src/math?h=rs-1.0
license:   http://git.musl-libc.org/cgit/musl/tree/COPYRIGHT?h=rs-1.0

Potential enhancements:
- Check how many useful libm implementations are still missing and consider
  adding them (some of them already work via the MS runtime).
- Consider putting libm implementations in an actual libm.a file, or add a dummy
  one such that build processes which try to link with libm will not fail.

9c52ba48b3 win: math.h: fix fpclassify/signbit/etc - use C instead of broken asm
The asm code cannot currently be used with tcc since tcc doesn't support 't'
constraint.

Use inline C implementation instead, place it win32/include/tcc/tcc_libm.h, and
include it from win32/include/math.h.

Since fpclassify now works, it also fixes few other macros which depend on it.
Implicitly fixed: isfinite, isinf, isnan, isnormal.

The implementations were taken from musl-libc rs-1.0 (MIT license).

6e261a107c win: math.h: isnan: use macro, similar to others (still broken)
It was broken due to tcc not able to compile asm with 't' constraint, and it's
still broken because fpclassify on which it now depends has the same issue. Next
commit will fix this.

        tcc internals inside a code comments.

73faaea227 i386-gen: preserve fp control word in gen_cvt_ftoi
- Use runtime function for conversion
- Also initialize fp with tcc -run on windows

This fixes a bug where
  double x = 1.0;
  double y = 1.0000000000000001;
  double z = x < y ? 0 : sqrt (x*x - y*y);
caused a bad sqrt because rounding precision for the x < y comparison
was different to the one used within the sqrt function.

This also fixes a bug where
  printf("%d, %d", (int)pow(10, 2), (int)pow(10, 2));
would print
  100, 99
