- utility functions strncat_from_pascal(), etc renamed strncat_from_pac().
- termmode script enhanced to chhpterm script including memory lock & more
- Some consolidation:
   - MPE groups OPERATOR and SCRIPTS consolidated into bin directory;
       executable goes in HPBIN group if Priv Mode is required; symbolic link
       is created.
   - MPE group XL contents (LIBCPXL) moved to HPBIN group


WHAT'S NEW in version 6.0.6 - November 9, 1999

  - STRMCAT message catalog added - contains error messages of all intrinsics
      in MPE Intrinsics manual which do not use the status variable (where
      HPERRMG intrinsic would be used to retrieve error message)
- UPDATED:
  - clear command updated to clear all the screen buffer, not just what's
      being displayed
  - ld command updated to handle -L and -l options
  - mmap(), etc. updated to handle MAP_ANONYMOUS, MAP_FILE, & MAP_VARIABLE
  - pmpeerror() and strmpeerror() moved from include directory to their own

      setsigint() with no arguments is what's most frequently used
  - strmpeerror() updated to retrieve error message from new STRMCAT message
      catalog
  - uname() enhanced with id and license fields like HP-UX
  - single LIBCPXL XL created combining all functions which require Priv Mode
  - mpeerrno.h & strmpeerror() updated for new MPE 6.0 intrinsics
  - -DDEBUG removed from include/Make.defines as default
  - all header files updated to handle C++


WHAT'S NEW in version 6.0.5 - July 14, 1999
- whoami script revised to return only first field of 'who am i'
- stat() under unix_notavail sets all non-POSIX fields

WHAT'S NEW in version 6.0.4 - March 26, 1999
- reduced # of libraries:
  - libenv deleted;  getenv() moved to libposix60.

- pMPEerror() & strMPEerror() renamed to pmpeerror() & strmpeerror()
- in Makefiles: $(@:d) & $(@:f) changed to more common $(@D) & $(@F)
- test programs linking in wrapper now end in tw, used to be ts


WHAT'S NEW in version 6.0.3 - March 15, 1999
- stubs for 8 terminal control functions deleted from libc.a.  All they did was
    return a "Function not implemented" error.  The wrappers for these functions
    were moved from directory posix.1_notimpl to directory posix.1_notavail.
- ld2 script enhanced to handle -a archive_shared, -a default, -a shared_archive


WHAT'S NEW in version 6.0.0
- raise(), an ISO C function (not POSIX), has been fixed (it was defective)
- fcntl() wrapper which handles both files and sockets
- mmap(), msync(), and munmap() wrappers
- ar2 script (to use instead of ar command when ar is defective)
- ld2 script (to build a shared library or link an executable)



WHAT'S INCLUDED

 8 POSIX functions defective in libc.a      (posix.1_defects directory)
 7 POSIX functions found in libc.a, but return "Function not implemented" error
                                            (posix.1_notimpl directory)
16 POSIX functions not available on MPE/iX  (posix.1_notavail directory)
32 Unix (not POSIX or Standard C) functions (unix_notavail directory)
14 utility functions                        (util directory)
