Additional hint for a Singular version before 3-0-2

     64bit systems (DecAlpha/Linux, Itanium/Linux, Opteron/Linux)
     (obsoleted by 3-0-2):
       ./configure -without-MP
       Special hints for 64bit systems:
       To compile Singular yourself on a 64 bit system:
       - MP is not yet ported to 64bit architekture, so built without it:
         ( add --without-MP to the options of configure)
       - after configuring goto omalloc and do a
         make install_all
       -  edit kernel/Makefile and Singular/Makefile and
          delete -DOM_NDEBUG from CFLAGS and CXXFLAGS and
          change all -lomalloc_ndebug to -lomalloc
