Re: [Tinycc-devel] Error compiling with mingw 4.4.1

I can trace the problem to the file "tccpp.h" in the function

ST_FUNC int tcc_preprocess(TCCState *s1)

in the line
         line_ref = (file_ref = file)->line_num;

The solution is change the definition of file_ref from

       BufferedFile *file_ref
      static BufferedFile *file_ref;

After this change, i can compile ok with mingw 4.4.1.

(i don't know if this was fixed in later's mingw distributions, someone report the same problem until mingw 4.5 according the mail archives. Also the archives give others workarounds as change the level of optimization (no Os) or use the option -fno-tree-vrp for avoid the vrp optimization. Both alternatives are valid, too.)

I try to compile the mob with mingw-4.4.1 and give me this :

See <http://www.tdragon.net/recentgcc/bugs.php> for instructions.

However with my old mingw 3.4.5 compile ok. Any clue ?.
