22# compiler flags for hp-ux.  Instead, the user should set CXXOPTS
23# or run runtest with --target_board unix/gdb:debug_flags="..."
24# to choose the compiler flags.
25#
26# The interesting compiler flags are: "aCC +A -Wl,-a,-archive" .
27# Static-linked executables use a different mechanism to get the
28# address of the notification hook in the C++ support library.
