24 # - library_path_var is the platform dependent runtime library path variable
25 # - library_path_value is a colon separated list of directories that contain
26 # the libraries at installation time (use this instead of -rpath)
27 # - prefix is the base directory at installation time
28 # - compile_command is a C compiler compilation and linking command
29 # - srcdir is the directory where to find relocwrapper.c and its dependencies
30 # - builddir is the directory where to find built dependencies (namely,
31 # alloca.h and stdbool.h)
32 # - config_h_dir is the directory where to find config.h
33 # - exeext is platform dependent suffix of executables
34 # - install-command is the install command line, excluding the final destprog
35 # - destprog is the destination program name
36 # install-reloc renames destprog to destprog.bin and installs a relocating
37 # wrapper in the place of destprog.
