* harbour/include/Makefile
    + added hbapicls.h

  * harbour/include/hbapi.h
  * harbour/source/vm/garbage.c
    * added some testing macros

  * harbour/include/hbmath.h
    * HB_MATH_ERRNO enabled for MINGW build. Seems that MinGW doesn't
      activate math error handler and only sets errno

  * harbour/include/hbtypes.h
  * harbour/source/vm/maindllp.c
    ! fixed VM_PROCESS_SYMBOLS_EX definition
    * cleaned a little bit code to not return uninitialized values
      when original function cannot be detected

  * harbour/source/compiler/genc.c
    * minor modifications

  * harbour/source/rtl/math.c
    ! fixed possible memory leak
    * indenting

  * harbour/source/vm/classes.c
    ! fixed possible GPF in __GETMSGPRF
    * use only one function for method name hashing

  * harbour/source/vm/hvm.c
    * minor fix
