- The -bhalt:4 option supposedly changes the level at which ld will abort,
- but it also suppresses warnings about multiply defined symbols and is
- used by the AIX cc command. So we use it here.
-
- -bnodelcsect undoes a poor choice of default relating to multiply-defined
- csects. See AIX documentation for more information about this.
-
- -bM:SRE tells the linker that the output file is Shared REusable. Note
- that to actually build a shared library you will also need to specify an
- export list with the -Wl,-bE option.
-
- If -mcpu=common, export the architecture dependent multiply/divide routines
- as per README.RS6000. */
