# We need to set ld library path in the environment. Currently,
# unix.exp doesn't set the environment correctly for all systems.
# It only sets SHLIB_PATH and LD_LIBRARY_PATH when it executes a
# program. We also need the environment set for compilations, etc.
#
# On IRIX 6, we have to set variables akin to LD_LIBRARY_PATH, but
# called LD_LIBRARYN32_PATH (for the N32 ABI) and LD_LIBRARY64_PATH
# (for the 64-bit ABI). The same applies to Darwin (DYLD_LIBRARY_PATH),
# Solaris 32 bit (LD_LIBRARY_PATH_32), Solaris 64 bit (LD_LIBRARY_PATH_64),
# and HP-UX (SHLIB_PATH). In some cases, the variables are independent
# of LD_LIBRARY_PATH, and in other cases LD_LIBRARY_PATH is used if the
# variable is not defined.
#
# Doing this is somewhat of a hack as ld_library_path gets repeated in
# SHLIB_PATH and LD_LIBRARY_PATH when unix_load sets these variables.
