Yes, it uses getopt(), whose standard behaviour under unix/macOS is to return (-1) as soon as the next argument parsed doesn't match one of the provided options. Subsizer's option parser then drops through to code that treats the remainder of the argument list as input files.

Looks like windows doesn't actually have a standard getopt()? At least, not going by some cursory googling…

iAN: I guess the command line handler code is system dependent. Different libraries, or so.

cjam: weird, works for me on the win32 exe.
> subsizer test.1200 -otest.sub.prg -Xdirty,jmp=0x1200

> unp64 -v test.sub.prg

T.L.R. Subsizer 0.6 / dirty, unpacker=$00ee
Entry point: $0815
pass1, find unpacker: $00ee
Iterations 4975 cycles 15663
pass2, return to mem: $1200
Iterations 778071 cycles 2555446
saved $0b00-$91c0 as test.sub.prg.1200

and works in vice.

Minor gotcha that had me scratching my head for a bit: any options after the input file will be silently ignored.

Eg, don't do this:
subsizer in.prg -oout.prg -Xdirty,jmp=0x0801

(it will just produce an a.out and ignore the SFX flags)

One way to filter the .h files from the args passed to cc is to change the build rule to

$(CC) -O3 -march=native -Wall -o$@ $(filter-out $(wildcard *.h),$^) -lm

Added an improved set of makefiles that should be more portable. Thanks to frantic for testing.

Also, thanks for the win32 builds that keep on coming! Is that you iAN?

@frantic: Thanks for reporting. The build system is somewhat of a kludge, I know. Wouldn't have guessed that -o space requirement. Will fix for next release and test with clang.

To get this to compile on OSX without manually specifying some other compiler version than the default one I had to remove all the .h files from the $^ list of files passed to cc in the makefile. Otherwise the following error is thrown:

clang: error: cannot specify -o when generating multiple output files

I also had to change:
$(LD) -r $^ -o$@

...in the makefile in the sfx dir to:
$(LD) -r $^ -o $@

...in order to avoid the following error:
ld -r detect_start.o generate_sfx.o fold.o -osfx.o
ld: unknown option: -osfx.o
make: *** [sfx.o] Error 1
