* gcc.c (set_collect_gcc_options): New function, split out from
main.
Ignore elided switches.
(do_spec_1): Invoke before executing command.
(set_input): Export.
Move declaration ...
* gcc.h (set_input): ... here.
* config/alpha/osf.h (ASM_FINAL_SPEC): Use %U.s to refer to input
file.

* jvspec.c (jvgenmain_spec): Cannot use %umain, breaks
ASM_FINAL_SPEC.
(lang_specific_pre_link): Use set_input to set input_filename.
Append `main' here.
* jvgenmain.c (usage): Append literal `main' to CLASSNAME.
(main): Fix definition.
Strip `main' from classname.
Fixes PR java/227.

* lex.h: Don't include setjmp.h. Don't define
