I'm using gcc version 1.35 under Ultrix 3.0 on a Vax 8530.
I'm not on bug-gcc.
The standard "cc" found on ultrix will not allow you to use the -o
option with an argument that has a .o suffix. This includes when you
use the -c option at the same time. This seems overly facist.
gcc will allow you to use the -o option with a .o suffix all the time.
If you specify an output file with the same name as your .c file but
with a .o suffix instead of .c, and you aren't using -c, then your
compile will always fail because ld will overwrite the object file.
This seems overly liberal.
In summary:
Not allowed by cc:
cc foo.c -c -o foo.o ; should be allowed
Allowed by gcc:
cc foo.c -c -o foo.o ;good
cc foo.c -o bar.o ;ok
cc foo.c -o foo.o ;probably shouldn't be allowed
