 # Make sure that your configuration DOES NOT set ANY gcc-related
 # variables.  ksh93 will not compile if you set even the seemingly
 # most unrelated variable related to gcc configuration.  This means
 # especially any flag which attempts to set the cputype.  Setting the
 # cputype does absolutely nothing except cause systems to fail in
 # horrible ways.  For any modern processor, setting the cputype only
 # serves to expose gcc bugs and does nothing to speed up any known
 # program.  If you are really unconvinced, go ahead but do not
 # complain to me about it.
