bbcb54a1f4 replace PARSE_FLAG_ASM_COMMENTS with PARSE_FLAG_ASM_FILE 
after "assign PARSE_FLAG_ASM_COMMENTS only for asm files"
    functions of this flags are identical

7c27186a83 Revert "* and #pragma pop_macro("macro_name")" 
- pop_macro incorrect with initially undefined macro
- horrible implementation (tcc_open_bf)
- crashes eventually (abuse of Sym->prev_tok)

- the (unrelated) asm_label part is the opposite of a fix
  (Despite of its name this variable has nothing to do with
  the built-in assembler)

This reverts commit 0c8447db79.

0c8447db79 * and #pragma pop_macro("macro_name") 
* give warning if pragma is unknown for tcc
    * don't free asm_label in sym_free(),
      it's a job of the asm_free_labels().

    The above pragmas are used in the mingw headers.
    Thise pragmas are implemented in gcc-4.5+ and current
    clang.

a9fda392a0 Parse assembler .hidden directive 
This makes TCCs assembler understand the '.hidden symbol' directive
(and emits a STV_HIDDEN ELF symbol then).

944627c479 configure: cleanup 
- add quotes: eval opt=\"$opt\"
- use $source_path/conftest.c for OOT build
- add fn_makelink() for OOT build
- do not check lddir etc. on Windows/MSYS
- formatting

config-print.c
- rename to conftest.c (for consistency)
- change option e to b
- change output from that from "yes" to "no"
- remove inttypes.h dependency
- simpify version output

Makefile:
- improve GCC warning flag checks

tcc.h:
- add back default CONFIG_LDDIR
- add default CONFIG_TCCDIR also (just for fun)

tccpp.c:
- fix Christian's last warning
  tccpp.c: In function ‘macro_subst’:
  tccpp.c:2803:12: warning: ‘*((void *)&cval+4)’ is used uninitialized
     in this function [-Wuninitialized]
  That the change fixes the warning doesn't make sense but anyway.

libtcc.c:
- tcc_error/warning: print correct source filename/line for
  token :paste: (also inline :asm:)

lddir and multiarch logic still needs fixing.

b8adf0090e Move asm label functions from tccasm.c to tccgen.c 
* Move functions parse_asm_str and asm_label_instr from tccasm.c to
  tccgen.c
* Remove CONFIG_TCC_ASM_LABEL macro as asm label are available on all
  archs.
See:
http://lists.nongnu.org/archive/html/tinycc-devel/2010-09/msg00026.html
for the rationale.

9b09fc376e Add support of asm label for functions. 
Add support for asm labels for functions, that is the ability to rename
a function at assembly level with __asm__ ("newname") appended in
function declaration.
