Compiling warnings (one error at least)

[Marcelo Matus]

I just compile the commoncpp2-1.0.1 version and
I've got the following warnings:


****************

thread.cpp(303): warning #418: declaration requires a typedef name
 };
  ^

file.cpp(342): warning #592: variable "pos" is used before its value is set
     lseek(fd, pos, SEEK_SET);
               ^
serial.cpp(449): warning #858: type qualifier on return type is meaningless
 const int Serial::aRead(char *Data, const int Length)
           ^

serial.cpp(454): warning #858: type qualifier on return type is meaningless
 const int Serial::aWrite(const char *Data, const int Length)
           ^
engine.cpp(119): warning #186: pointless comparison of unsigned integer 
with zero
           if (myZStream.avail_out >= 0)
                                   ^
unix.cpp(468): warning #187: use of "=" where "==" may have been intended
          if( errno = EINPROGRESS )
              ^

************************

and at least the last one (unix.cpp) seems to be an error. Also, the 
warning for
the  file.cpp file seems to be important.
