  COMMENTS:
  This APAR addresses the following MakeTPF issues:
  
  1) Linking C or C++ objects with BAL objects in the same BAL
  shared object is not supported. When C++ and BAL objects are
  linked in the same shared object, the loader will show an error
  because of the __TPF_soinit symbol that gets included from the
  startup code. Similarly, when C and BAL objects are linked in
  the same shared object, errors can occur when the C object
  includes imported data or constructors.
  2) The default GCC 4.6 compile options should not include
  -Wno-strict-aliasing.
  3) The maketpf_prereq script does not recognize GCC 4.6 as a
  supported compiler version.
  4) The mysqlcomp makefile does not correctly locate the
  compiler include directory for gcc 4.6.
  5) The maketpf_gen_sqa_uss and maketpf.rules file contain lines
  over 255 characters in length. A request has been made to
  shorten the line length below 255 characters in those files.
  6) When compiled using GCC 4.6, cftcon.c in CTMW shows a
  warning for a mismatched prototype.
  

Problem conclusion

• SOLUTION:
  The following updates are included in this APAR:
  1) A new error message (MTPF0241E) will be issued when linking
  a BAL shared object if the BAL shared object includes both BAL
  and C or C++ object code. This new audit does not apply to C
  shared objects that include TPFISOC assembler code.
  2) The -Wno-strict-aliasing option has been removed as a
  default for the GCC 4.6 compiler.
  3) The maketpf_prereq script has been updated to recognize GCC
  4.6 as a supported compiler version.
  4) The mysqlcomp makefile has been updated to correctly locate
  the GCC 4.6 compiler include directory.
  5) The maketpf_gen_sqa_uss and maketpf.rules files have been
  modified to reduce the maximum line length below 255 characters.
  6) The mismatched prototype warning has been corrected in the
  GCC 4.6 compiles of cftcon.c in CTMW.
