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.

003c532bf3 fix for the #include_next, v4 (final)
This version looks rigth. Comparing to the original
    algorithm:

    1) Loop breaking. We remember a start point after wich
    we can try next path. Do not search include stack after
    this.

    2) But compare next file patch with the start point.
    Skip if it the same. Remove "./" before comparing.

    PS: a problems with compaling a coreutils-8.24.51-8802e
    remain. There are errors messages like:
    src/chgrp
        src/chown-core.c:42: multiple definition of `make_timespec'
        src/chgrp.c:42: first defined here
    A problem is in the lib/config.h
        #define _GL_INLINE_ extern inline // gcc
        #define _GL_INLINE_ inline        // tcc

    A long description from the lib/config.h
    * suppress extern inline with HP-UX cc, as it appears to be broken
    * suppress extern inline with Sun C in standards-conformance mode
    * suppress extern inline on configurations that mistakenly use
      'static inline' to implement functions or macros in standard
      C headers like <ctype.h>.

    GCC and Clang are excluded from this list. Why not tcc?

ad1c01f96c fix for the #include_next, v3
don't give an error and simply ingnore directive
  if we detect a loop of the #include_next.

  With this aproach coreutils-8.24.51-8802e
  compiles, but with errors:
  	lib/libcoreutils.a: error: 'xnmalloc' defined twice
	lib/libcoreutils.a: error: 'xnrealloc' defined twice

6b9490b6ff fix for the #include_next, v2
A more correct fix. This one don't break old logic.
    But if include file is not found, we try to search
    again with the new compare rule.

f0b7566181 tccelf.c: Reset sym after call to build_got.
The call to build_got can cause symtab_section->data to be reallocated
(build_got -> add_elf_sym -> put_elf_sym -> section_ptr_add ->
section_realloc -> tcc_realloc). This is not obvious on a cursory
inspection, but fortunately Valgrind spotted it immediately.
Are there other, similar bugs that Valgrind did not detect?
