be7c870718 Fix va_end() definition: must be an expression of type void
Also added a test yielding a failure with the previous definition,
i.e. when using: (va_end(ap));

The test also checks potentially incorrect va_start() definition.

7369cfc490 Revert "Add max_align_t to stddef.h"
max_align_t is C11 not C99 and the name is not reserved by C99.

This reverts commit 7eceba178d.

da8c62f75d various stuff
win32/Makefile ("for cygwin") removed
- On cygwin, the normal ./configure && make can be used with either
  cygwin's "GCC for Win32 Toolchain"
      ./configure --cross-prefix=i686-w64-mingw32-
  or with an existing tcc:
      ./configure --cc=<old-tccdir>/tcc.exe

tcctest.c:
- exclude test_high_clobbers() on _WIN64 (does not work)

tests2/95_bitfield.c:
- use 'signed char' for ARM (where default 'char' is unsigned)

tests:
- remove -I "expr" diff option to allow tests with
  busybox-diff.

libtcc.c, tcc.c:
- removed -iwithprefix option.  It is supposed to be
  combined with -iprefix which we don't have either.

tccgen.c:
- fix assignments and return of 'void', as in
     void f() {
         void *p, *q;
         *p = *q:
         return *p;
     }
  This appears to be allowed but should do nothing.

tcc.h, libtcc.c, tccpp.c:
- Revert "Introduce VIP sysinclude paths which are always searched first"
  This reverts commit 1d5e386b0a.

  The patch was giving tcc's system includes priority over -I which
  is not how it should be.

tccelf.c:
- add DT_TEXTREL tag only if text relocations are actually
  used (which is likely not the case on x86_64)
- prepare_dynamic_rel(): avoid relocation of unresolved
  (weak) symbols

tccrun.c:
- for HAVE_SELINUX, use two mappings to the same (real) file.
  (it was so once except the RX mapping wasn't used at all).

tccpe.c:
- fix relocation constant used for x86_64 (by Andrei E. Warentin)
- #ifndef _WIN32 do "chmod 755 ..." to get runnable exes on cygwin.

tccasm.c:
- keep forward asm labels static, otherwise they will endup
  in dynsym eventually.

configure, Makefile:
- mingw32: respect ./configure options --bindir --docdir --libdir
- allow overriding tcc when building libtcc1.a and libtcc.def with
      make XTCC=<tcc program to use>
- use $(wildcard ...) for install to allow installing just
  a cross compiler for example
      make cross-arm
      make install
- use name <target>-libtcc1.a

build-tcc.bat:
- add  options: -clean, -b bindir

This reverts commit 52622c3c03.

41349948f8 win64: fix va_arg
fixes 5c35ba66c5

Implementation was consistent within tcc but incompatible
with the ABI (for example library functions vprintf etc)

Also:
- tccpp.c/get_tok_str() : avoid "unknown format "%llu" warning
- x86_64_gen.c/gen_vla_alloc() : fix vstack leak

f01373765b stdbool.h: Make conformant to ISOC99
For conformance to ISO C the stdbool.h header has to provide
the macro __bool_true_false_are_defined (defined to 1).  Yep,
that name is really in the standard.

3900b235e0 x86_64: pass va_list as pointer
The ABI requires that va_list is passed as a pointer although its
contents is a kept in a structure. Therefore make it a single element
array.

262eec3e83 Fixed the LDBL_* macros in include/float.h for x86-64: as said
when x86-64 support was added, "for long double, we use x87 FPU".
And indeed, tests show that Intel's extended precision is used,
not double precision.

6ee366e765 Fixed x86-64 long double passing.
long double arguments require 16-byte alignment on the stack, which
requires adjustment when the the stack offset is not an evven number of
8-byte words.

1caee8ab3b Sorted out CMake on x86-64 and fixed silly XMM# bug introduced when working on Win64 stdargs.
I removed the XMM6/7 registers from the register list because they are not used
on Win64 however they are necessary for parameter passing on x86-64. I have now
restored them but not marked them with RC_FLOAT so they will not be used except
for parameter passing.

5c35ba66c5 64-bit tests now pass (well, nearly).
tcctest1-3 fail, but this appears to be due to bugs in GCC rather than TCC
(from manual inspection of the output).

b89793d10a win32: _mingw.h: do not undef NULL
Not wise if stddef.h was already included. This is related to commit

    3aa26a794e

Instead hack stddef.h to have identical definition and thus
avoid the issue mentionned there.

- add a test case based on the bug report

Also, remove gcc specific sections in headers. and
instead change tests such that gcc does not use them.
