# 32-bit PA-RISC HP-UX embeds the -L pathname of libs we link with, so
# we compensate for it with +cdp ../: and +cdp ./:. Yes, these rewrite
# rules imply that we can only link one level down in catalog structure,
# but that's what takes place for the moment of this writing. +cdp option
# was introduced in HP-UX 11.x and applies in 32-bit PA-RISC link
# editor context only [it's simply ignored in other cases, which are all
# ELFs by the way].
