# 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.

# Do not update this port to 93v. 93v was an abandoned beta when
# David Korn left the project. It was subsequently reverted to 93u.
