# This is for the HP-UX 10.x and 11.x using the aC++ compiler.
#
# For 10.x, most of the difference for threaded vs. non-threaded is
# contained in ace/config-hpux-10.x.h.  However, to build without threads,
# you should run the make with "threads=0" since the default is to build
# with threads.
#
# HP-UX 11 supports both 32-bit and 64-bit builds, regardless of which
# architecture the build is done on.  This file is set up to build native
# to the machine it's running on.  To cross-build for another platform, add
# "buildbits=32" to make a 32-bit build, and "buildbits=64" to do a 64-bit
# build.  Note that if you explicitly specify a 64-bit build, the option
#  -Wl,+vnocompatwarnings is added to shut up the "At least one PA 2.0 object
# file detected..." messages.
