deb7a3fc73 tcc.c:main() free all & etc...
tcc.c:
- be nice to leak checkers
tcctools.c:
- remove unused TCCState params
tccrun.c:
- call bound_exit() after signals to let it free mem
tccelf.c:
- use section_add() instead of section_ptr_add() when
  more appropriate
tccpp.c:
- use size_t to align tal_header naturally
- 'POINTER_SIZE' and 'PTR_SIZE' in the same source is confusing
- "char file_name[TAL_DEBUG_FILE_LEN + 1];" looks silly.
- next_nomacro(): skip UTF8 BOM at BOF
tccgen.c:
- get rid of STMT_EXPR clause on top of block
- warn with useless type like 'int;'
- move skip()'s in block() for better error line-info
- BIT_SIZE bits are meaningful only with VT_BITFIELD
  (not with enums for example)
workflow/test-win32:
- build with MSVC using build-tcc.bat also
alloca.S:
- fix 'off by one' problem on win32 (must touch current page
  too because the 'push %edx' at the end could touch the next page)
- must not align greater than 4 when used for struct args
  (i386-gen.c:gfunc_call())
libtcc.c:
- accept -g1dwarf (dwarf output, only line info)

Some checks are pending

I updated the tests/gcctestsuite.sh a bit.
before:
  3329 test(s) ok.
  210 test(s) skipped.
  168 test(s) failed.
  28 test(s) exe failed.
after:
  3331 test(s) ok.
  299 test(s) skipped.
  79 test(s) failed.
  26 test(s) exe failed.

I found some small problems:
include/tccdefs.h: Add alloca definition for i386 and x86_64
lib/alloca.S/lib/alloca-bt.S: align i386 alloca to 16 bytes.
			      i386_gen.c vla code and gcc do the same.
x86_64-gen.c: fix typo in comment

271 insertions(+), 292 deletions(-), -21 lines, -5 files
Also:
- tccdefs.h: WIN32: less (no) __builtins
- libtcc.c: simply ignore -arch
