- #include "?????.h"

- followed by any really system-specific defines (or overrides of

- is defined here with only the defined -Dunix and -DSVR4. You should
- probably override that in your target-specific ?????svr4.h file
- with a set of defines that includes these, but also contains an
- appropriate define for the type of hardware that you are targeting.

support here for as many of the other svr4 linker options as seems
reasonable, given that some of them conflict with options for other
svr4 tools (e.g. the assembler). In particular, we do support the
- -z*, -V, -b, -t, -Qy, -Qn, and -YP* options here, and the -e*,
- -l*, -o*, -r, -s, -u*, and -L* options are directly supported
- by gcc.c itself. We don't directly support the -m (generate load
- map) option because that conflicts with the -m (run m4) option of
- the svr4 assembler. We also don't directly support the svr4 linker's
- -I* or -M* options because these conflict with existing GCC options.
- We do however allow passing arbitrary options to the svr4 linker
- via the -Wl, option. We don't support the svr4 linker's -a option
- at all because it is totally useless and because it conflicts with
- GCC's own -a option.
