grischka da0d43903b review recent commits 
tccpp.c:
 - revert "Preprocessor fix + new testcase"
   Fix was not a fix and nobody could understand the test.
   This reverts 6379f2ee76
 - better fix and add new test (pp/18.c)

tccgen.c:
 - remove global variables 'in_sizeof', 'constant_p'
 - rework comma expression (gexpr())
 - merge func/data 'alias_target' codes
   (See 08c777053c)
 - move call to do_Static_assert()
 - better error: "expression expected before '%s'"
 - fix "statement after label"
    - remove unnecessary second parameter to block()
    - remove unnecessary call to decl()
    - revert changes to old C89 test file
    See 7f0a28f6ca

tccelf.c:
 - rework "...make undefined global symbol STT_NOTYPE"
   (See f44060f8fc)
 - move tccelf_add_crtbegin() from libtcc.c

tcctest:
 - unfix K&R fix (keep old look of K&R functions)

tccrun.c:
 - exit(0) returns 0

libtcc.c:
 - move #defines for -dumpmachine
 - more explicit error "file not found"
   (as opposed to error while loading file)

tccpe.c, x86_64-gen.c, i386-asm.c, tccasm.c:
 - use R_X86_64_PLT32 for functions on x86_64-win32

tccdefs.h
 - empty #defines for _Nonnull, __has_builtin(), etc.

configure:
 - Simpler "macOS .dylib ... VERSION letters."
   (See 6b967b1285)

Makefile:
 - macOS version also
 - add cross searchpaths for packages

build.yml:
 - disable codesign on macos-11 (doesn't seem to work)

/* tccdefs.h
Nothing is defined before this file except target machine, target os
and the few things related to option settings in tccpp.c:tcc_predefs().
This file is either included at runtime as is, or converted and
included as C-strings at compile-time (depending on CONFIG_TCC_PREDEFS).
Note that line indent matters:
- in lines starting at column 1, platform macros are replaced by
corresponding TCC target compile-time macros. See conftest.c for
the list of platform macros supported in lines starting at column 1.
- only lines indented >= 4 are actually included into the executable,
check tccdefs_.h.
