############### Define platform-specific directory ring-down ##################################
# The purpose of this file is to define the source directories
# for each platform
# It also defines
# - gt_build_type <--- significance for 32bit Linux
# - gt_use_nsb 		 <--- 32bit Linux and CYGWIN use NSB
# - gt_build_xfer_desc <- ia64/x86_64 Linuxen and HPUX IA64 use this

# Preserve sanity ###############################################
# 32bit Linux/CYGWIN are the only GT.M builds that use
# non-shared binaries, aka nsb.  32bit Linux builds are
# the most error prone since x86 starts at i386 till i686
# and you can build 32bit on x86_64 by setting OBJECT_MODE
# to 32
# We must do these checks first to ID NSB builds and 32bit
# linux builds which throw a monkey wrench into the whole
# process.
