* config/global.mk
    * set HARBOUR=F:100 during build process in OS2 builds - it increases
      maximum number of open handles per process from 20 to 100 so it should
      be possible to use -j<n> switch during Harbour compilation - please
      test, i.e.:
         os2-make -j3

  * contrib/xhb/hbcompat.ch
    ! fixed pp rules for Str(,,, <lStrip> ) translation

  * include/hbapifs.h
  * src/rtl/filesys.c
    + added new C function:
         HB_FHANDLE hb_fsOpenEx( const char * pszFileName, HB_FATTR nAttr,
                                 HB_USHORT uiFlags );
    * minor cleanup

  * include/hbmemory.ch
  * src/vm/fm.c
    + added two new actions for Memory() function:
         HB_MEM_STATISTICS - return non 0 value if FM statistic is enabled
         HB_MEM_ISLIMIT    - return non 0 value if used memory limit is
                             supported
    + added new PRG function:
         __fm_allocLimit( [ <nNewLimit> ] ) -> <nPrevLimit>
      It allows to set limit for maximum used memory in some memory
      managers, -1 means no limit.
      Now it works with DLMALLOC and in ST mode it's limit for memory
      allocated from system for whole application. In MT mode when
      HB_FM_DLMT_ALLOC (default for DLMALLOC) is enabled it's limit for
      single MSPACE (Harbour allocates 16 MSPACES and balance them
      between threads to improve scalability) so it's rather per thread
      limit. If memory statistic module is enabled during Harbour build
      process then this limit works with any memory manager and defines
      limit for total memory allocated by Harbour application regardles
      of MT or ST mode.

  * src/vm/hvm.c
    * use HB_MEM_STATISTICS instead of HB_MEM_USEDMAX to check if memory
      statistic module is enabled
